Diisopropylsilyl ditriflate and di-tert-butylsilyl ditriflate, each available from the appropriate dialkylchlorosilane and triflic acid, react with 1,2-, 1,3-, and 1,4-diols usually at 25 deg C in the presence of 2,6-lutidine to provide the corresponding dialkylsilylene derivatives in high yield.These derivatives, which are readily deprotected under mild conditions, can be utilized for selective reactions of polyhydroxy compounds.
