The reactions of acylsilanes with KCN under liquid-liquid phase-transfer catalytic conditions proceeded smoothly via the Brook rearrangement to produce O-silylated cyanohydrin derivatives in excellent yields. We also found that Ξ±-cyano carbanions generated by the Brook rearrangement in the reaction
The reaction of 2,4,6-tribromophenol (ArOH) and a-bromo-oxylene (RBr) catalyzed by tetrabutylammonium bromide (QBr) was carried out in an alkaline solution of KOl-I/organic solvent two-phase medium. A peculiar phenomenon, in which the rate of a PTC/OH reaction does not change monotonously with the c
