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)
