Abstract: Organic silanes of formula (I) are prepared by reacting gammagly cidoxypropyltoialkoxysilane of formula (II) with a cpd. of formula (III) in the presence of a solvent and a base. In the formulas, R is C1-4 aliphatic alkyl; R1 and R3 are each phenyl, cyanide, -CO-CH3 or -CO2R4; R4 is C1-4 aliphatic alkyl. (I) are useful for stabilizing silicate in the antifreezing solution.
