One-pot synthesis and functionalization of polyynes via alkylidene carbenoids
Luu, Thanh,Morisaki, Yasuhiro,Tykwinski, Rik R.
, p. 1158 - 1162 (2008)
A one-pot, two-step method for the synthesis of diynes and triynes is reported. The reaction of a dibromoolefinic precursor with BuLi effects a Fritsch-Buttenberg-Wiechell rearrangement and generates a lithium acetylide intermediate, which is then trapped
A new procedure for the synthesis of aryl- or hetaryl-substituted conjugated diynes
Vasilevskii, S. F.,Fossatelli, M.,Kork, A. H. T. M. van der,Brandsma, L.
, p. 307 - 309 (2007/10/02)
On treatment with two equivalents of NaNH2 in liquid ammonia the enyne sulfides RCC-CH=CHSEt (cis-isomers, where R is an aryl or a hetaryl) affords sodium salts of 1,3-diynes.The latter react with ethyl bromide to produce disubstituted diynes RCC-C
