The silanols formed on the cleavage of organosilylprotectinggroups from organic compounds can be efficiently reconverted into the chlorosilanes used in the initial silylation reaction by treatment with SOCl2. The silanol tBuMe2SiOH is very readily removed from organic reaction mixtures as its remarkably volatile hemihydrate [tBuMe2SiOH]2·H2O.
通过用SOCl 2处理,可以将有机甲硅烷基保护基团从有机化合物上裂解下来形成的硅烷醇有效地转化为用于初始甲硅烷基化反应的氯硅烷。硅烷醇吨BuMe 2 SiOH基很容易地从有机反应混合物作为其显着挥发性的除去半水合物[吨BuMe 2 SiOH基] 2 ·H 2 O.
