ABSTRACT OF THE DISCLOSURE Improved process for the silylation of organic com- pounds with 1,1,1-trimethyl-N-(trimethylsilyl)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 cata- lysts are compounds with the general formula X-NH-Y wherein X represents a hydrogen atom, a trialkylsilyl group or an electron-withdrawing group and Y represents an electron- withdrawing group.
