Abstract

Mannich‐type reactions of imines with silicon enolates were found to be catalyzed by neutral salts such as sodium triflate in water as a suspension medium. Unusual kinetic behavior indicates that the presence of the Mannich adduct facilitates the rate of its formation.

HBF 4 -catalyzed Mannich-type reaction of silyl enolates with aldimines took place smoothly in aqueous organic solvent to afford b-aminocarbonyl compounds in high yields. The HBF 4 -catalyzed Mannich-type reaction also proceeded smoothly in water without organic solvent in the presence of a surfacta
