Text of the page (random words):
ally analogous to the e1cb mechanism of aliphatic compounds aryl bromides and iodides on the other hand generally appear to undergo elimination by a concerted syn coplanar e2 mechanism 18 19 the resulting benzyne forms addition products usually by nucleophilic addition and protonation generation of the benzyne intermediate is the slow step in the reaction 20 aryne coupling reactions allow for generation of biphenyl compounds which are valuable in pharmaceutical industry agriculture and as ligands in many metal catalyzed transformations 21 the metal arene product can also add to another aryne leading to chain growth polymerization using copper i cyanide as the initiator to add to the first aryne yielded polymers containing up to about 100 arene units 22 when leaving group lg and substituent y are mutually ortho or para only one benzyne intermediate is possible however when lg is meta to y then regiochemical outcomes a and b are possible if y is electron withdrawing then h b is more acidic than h a resulting in regioisomer b being generated analogously if y is electron donating regioisomer a is generated since now h a is the more acidic proton there are two possible regioisomers of benzyne with substituent y triple bond can be positioned between c2 and c3 or between c3 and c4 substituents ortho to the leaving group will lead to the triple bond between c2 and c3 para y and lg will lead to regioisomer with triple bond between c3 and c4 meta substituent can afford both regioisomers as described above nucleophilic additions can occur with regioselectivity although classic explanations to explain regioselectivity refer to carbanion stability following attack by the nucleophile 20 this explanation has been replaced by the aryne distortion model by houk and garg 23 24 25 in this model substituents cause geometric distortion of the ground state structure of the aryne leading to regioselective reactions consistent with reactions proceeding through early transition states pericyclic reactions of arynes edit benzyne undergoes rapid dimerization to form biphenylene some routes to benzyne lead to especially rapid and high yield of this subsequent reaction 13 17 trimerization gives triphenylene 26 benzynes can undergo 4 2 cyclization reactions when generated in the presence of anthracene trypticene results 11 in this method the concerted mechanism of the diels alder reaction between benzyne and furan is shown below other benzyne 4 2 cycloadditions are thought to proceed via a stepwise mechanism a classic example is the synthesis of 1 2 3 4 tetraphenylnaphthalene 27 tetrabromobenzene can react with butyllithium and furan to form a tetrahydroanthracene 28 diaryne reaction with furan 4 2 cycloadditions of arynes have been commonly applied to natural product total synthesis the main limitation of such approach however is the need to use constrained dienes such as furan and cyclopentadiene 14 in 2009 buszek and co workers synthesized herbindole a using aryne 4 2 cycloaddition 29 6 7 indolyne undergoes 4 2 cycloaddition with cyclopentadiene to afford complex tetracyclic product benzynes undergo 2 2 cycloaddition with a wide range of alkenes due to electrophilic nature of benzyne alkenes bearing electron donating substituents work best for this reaction 30 due to significant byproduct formation aryne 2 2 chemistry is rarely utilized in natural product total synthesis 14 nevertheless several examples do exist in 1982 stevens and co workers reported a synthesis of taxodione that utilized 2 2 cycloaddition between an aryne and a ketene acetal 31 mori and co workers performed a palladium catalyzed 2 2 2 cocyclization of aryne and diyne in their total synthesis of taiwanins c 32 bond insertion reactions of arynes edit the first example of aryne σ bond insertion reaction is the synthesis of melleine in 1973 33 other dehydrobenzenes edit if benzyne is 1 2 didehydrobenzene two further isomers are possible 1 3 didehydrobenzene and 1 4 didehydrobenzene 3 their energies in silico are respectively 106 122 and 138 kcal mol 444 510 and 577 kj mol 34 the 1 2 and 1 3 isomers have singlet ground states whereas for 1 4 didehydrobenzene the gap is smaller the interconversion of the 1 2 1 3 and 1 4 didehydrobenzenes has been studied 34 35 a 1 2 to 1 3 didehydrobenzene conversion has been postulated to occur in the pyrolysis 900 c of the phenyl substituted aryne precursors 34 as shown below extremely high temperatures are required for benzyne interconversion 1 4 didehydroarenes edit in classical 1 4 didehydrobenzene experiments heating to 300 c 1 6 d2 a readily equilibrates with 3 2 d2 b but does not equilibrate with c or d the simultaneous migration of deuterium atoms to form b and the fact that none of c or d is formed can only be explained by a presence of a cyclic and symmetrical intermediate 1 4 didehydrobenzene 36 two states were proposed for 1 4 didehydrobenzene singlet and triplet with the singlet state lower in energy 37 38 triplet state represents two noninteracting radical centers and hence should abstract hydrogens at the same rate as phenyl radical however singlet state is more stabilized than the triplet and therefore some of the stabilizing energy will be lost in order to form the transition state for hydrogen cleavage leading to slower hydrogen abstraction chen proposed the use of 1 4 didehydrobenzene analogues that have large singlet triplet energy gaps to enhance selectivity of enediyne drug candidates 39 history edit the first evidence for arynes came from the work of stoermer and kahlert in 1902 they observed that upon treatment of 3 bromobenzofuran with base in ethanol 2 ethoxybenzofuran is formed based on this observation they postulated an aryne intermediate 40 first indication of benzyne wittig et al invoked zwitterionic intermediate in the reaction of fluorobenzene and phenyllithium to give biphenyl 41 42 43 this hypothesis was later confirmed 44 45 46 47 48 in 1953 14 c labeling experiments provided strong support for the intermediacy of benzyne 44 john d roberts et al showed that the reaction of chlorobenzene 1 14 c and potassium amide gave equal amounts of aniline with 14 c incorporation at c 1 and c 2 14 c labeling experiment shows equal distribution of products wittig and pohmer found that benzyne participate in 4 2 cycloaddition reactions 49 capture of benzyne as dienophile in diels alder reaction additional evidence for the existence of benzyne came from spectroscopic studies 3 benzyne has been observed in a molecular container 50 in 2015 a single aryne molecule was imaged by stm 51 1 3 didehydroarenes was first demonstrated in the 1990s when it was generated from 1 3 disubstituted benzene derivatives such as the peroxy ester 1 3 c 6 h 4 o 2 c o ch 3 2 3 breakthroughs on 1 4 didehydrobenzene came in the 1960s followed from studies on the bergman cyclization 36 this theme became topical with the discovery of enediyne cytostatics such as calicheamicin which generates a 1 4 didehydrobenzene 52 examples of benzynes in total synthesis edit a variety of natural products have been prepared using arynes as intermediates 14 nucleophilic additions to arynes have been widely used in natural product total synthesis indeed nucleophilic additions of arynes are some of the oldest known applications of aryne chemistry 14 nucleophilic addition to aryne was used in the attempted synthesis of cryptaustoline 1 and cryptowoline 2 53 the synthesis of the tetracyclic meroterpenoid liphagal involved an aryne intermediate 54 their approach employed an aryne cyclization to close the final ring of the natural product 14 multicomponent reactions of arynes are powerful transformations that allow for rapid formation of 1 2 disubstituted arenes despite their potential utility examples of multicomponent aryne reactions in natural product synthesis are scarce 14 a four component aryne coupling reaction was employed in the synthesis of dehydroaltenuene b 55 see also edit examples uses of aryne chemistry tricyclobutabenzene in methylcyclophane transition metal benzyne complex the pyridine
