Improved process for the silylation of organic compounds with 1,1,1-trimethyl-N-(trimethyl)silanamine by means of catalysis with certain nitrogen containing organic compounds. The organic compounds which may be silylated by the improved process are carrying one or more -OH, -NH or SH groups, for example alcohols, phenols, carboxylic acids, amines, amides, aminoacids and thiols. The nitrogen containing catalysts are compounds with the general formula
wherein X represents a hydrogen atom, a trialkylsilyl group or an electron-withdrawing group and Y represents an electron-withdrawing group. Novel trimethylsilylated thiols and novel trimethylsilylated 3'-substituted cephalosporanic acid derivatives are prepared by the improved process.
用 1,1,1-三甲基-N-(三甲基)硅烷胺与某些含氮有机化合物催化硅烷化的改进工艺。可通过改进工艺进行硅烷化的有机化合物带有一个或多个-OH、-NH 或 SH 基团,例如醇、酚、羧酸、胺、酰胺、氨基酸和硫醇。含氮催化剂是通式如下的化合物
其中 X 代表氢原子、三烷基硅烷基或抽电子基团,Y 代表抽电子基团。新型三甲基硅烷基化硫醇和新型三甲基硅烷基化 3'-取代头孢菌素酸衍生物是通过改进的工艺制备的。
