Abstract

Ga(I)-catalyzed C-C bond formations between allyl or allenyl boronic esters and acetals, ketals, or aminals have proceeded in high yields with essentially complete regio- and chemoselectivity by using a catalytic amount of Ga(0), a Ag(I) cocatalyst, crownether ligation, and ultrasonic activation.
