FIELD: chemistry.
SUBSTANCE: invention relates to synthesis of O-silylurethanes uses as starting material for synthesis of organic isocyanates and curing agents for silicone rubber. Disclosed is a method of producing O-silylurethanes through N-siloxycarbonylation of nitrogen-containing organic compounds using carbon dioxide and 3(5)-methyl-1-(trimethylsilyl)-1H-pyrazole or carbon dioxide and 1-(trimethylsilyl)-1H-imidazole as the N-siloxycarbonylating mixture. The process is carried out at temperature 55-65°C for 1.5-2.5.
EFFECT: simple process and high output of the end product.
