Efficient Activation of Acetals, Aldehydes, and Imines toward Silylated Nucleophiles by the Combined Use of Catalytic Amounts of [Rh(COD)Cl]2and TMS-CN under Almost Neutral Conditions
A new catalyst trimethylsilyl bis(fluorosulfonyl)imide has been prepared for aldol type reactions and allylation of acetals. The catalyst has been found to be more active than trimethylsilyl triflate for the above reactions.
