Novel reagents, bis(1-methoxy-2-methyl-1-propenyloxy) silanes () have been shown to be very useful bifunctional protecting agents for various types of H-acidic materials, such as diols, dithiols, diacids and their combined materials. The reaction proceeds rapidly under mild conditions to give the corresponding silylene derivatives in almost quantitative yields.
