Abstract

Novel α-Silyl-α-diazoacetates Containing a Silicon-Heteroatom Bond.-Silylation of diazoester (II) with the silyl triflates (I) gives the chlorosilyl diazoacetates (III). The latter can be easily transformed to azidosilyl-, isocyanatosilyl-, and isothiocyanatosilyl-substituted derivatives. The analogous chloro(dimethyl)silyl triflate generated from the silyl chloride (IX) and triflic acid, exhibits lower stability yielding a mixture of diazoacetates (X) and (XI).
