摘要

Abstract Lithium phenylacetylide (1a) and N 2 O 4 (2) at− 78 yield diphenylbutadiyne (6a) by oxidative coupling, phenylacetylene (7a) by oxidation and then solvent H-abstraction, and benzoyl cyanide (8) by dimerizative-rearrangement of nitroso (phenyl) acetylene (23). Nitro (phenyl) acetylene (3, R= Ph) is not obtained. Benzonitrile (9), a further product, possibly results from hydrolytic decomposition of nitroso (phenyl) ketene (27) generated from ...
