A new procedure for the synthesis of arylor hetaryl-substituted conjugated diynes
摘要:
On treatment with two equivalents of NaNH2 in liquid ammonia the enyne sulfides RC=C-CH=CHSEt (cis-isomers, where R is an aryl or a hetaryl) afford sodium salts of 1,3-diynes. The latter react with ethyl bromide to produce disubstituted diynes RC=C-C=CEt in high yields.
