Patent ID: 8871963

Claim:
A process for preparing carbamatoorganosilanes (S) of the general formula (7) in which a haloorganosilane (S1) of the general formula (8) X—R 2 —SiR 3 (3-x) (OR 4 ) x (8) is reacted in a reaction mixture with a metal cyanate (MOCN) and an alcohol (A) of the general formula (9) R 1 OH (9) in the presence of at least one aprotic solvent (L), where R 1 , R 3 and R 4 are each an unsubstituted or halogen-substituted hydrocarbyl radical having 1-10 carbon atoms, R 2 is a divalent unsubstituted or halogen-substituted hydrocarbyl radical which has 1-10 carbon atoms and is optionally interrupted by nonadjacent oxygen atoms, X is a halogen atom, and x is a value of 0, 1, 2 or 3, wherein removal of the solid metal halides formed as by-products and of any solid metal cyanate residues still present is preceded by distillative removal of at least 50% of the solvent (L).
