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.
新型试剂双(1-甲氧基-2-甲基-1-丙烯氧基)硅烷()已被证明是非常有用的双官能保护剂,适用于各种类型的H酸性材料,例如二醇,二硫醇,二酸及其组合材料。反应在温和条件下迅速进行,以几乎定量的产率得到相应的亚甲硅烷基衍生物。
