Bis(trimethylsilyl)formamide reacts with aldehydes in refluxing chloroform, or at room temperature with catalysis by trimethylsilyl trifluoromethanesulfonate, to give 1-acylamino-1-(trimethylsiloxy)alkanes; similar results are obtained with other bis(trimethylsilyl)amides, but surprisingly not with bis(trimethylsilyl)acetamide, and addition of bis(trimethylsilyl)formamide to ketones and acetals can also be accomplished using TMS triflate as catalyst.
