chloroform solution fo a dialk-1-enylmercury or an alk-1-enyltributylstannane results in rapid formation of a relatively unstable species, believed to be an alk-1-enyl-lead triacetat, which can be used for the α-alkenylation of β-dicarbonylcompounds.

vinyl-lead compound (2), generated in this way, reacted rapidly with β-keto ester (5) to give the α-(E)-styryl derivative (6) in synthetically useful yield. This procedure for the α-vinylation of (5) has been applied to the divinytmercury compounds (7)–(13), and to the synthesis of the α-(E)-styryl β-dicarbonylcompounds (28), (30), (32), and (34). Compounds (6), (28), (30), (32), and (34). Compounds (6)
