Abstract
1 ord its use as a potent acylating agent for hindered amines and tertiary alcohols3 and for the preparation of trimethylsilyl-substituted allenes and acetylenes. TMS-ketene reacts almost instantly in carbon tetrachloride with hindered amines such as diisopropyl-and isopropylcyclohexylaniine to produce the amide in essentially quantitative yield (eq a), the work-up consisting merely of
