Abstract
Abstract Alkoxysilyl ethers of 1,3-dicarbonyl cyclic compounds, such as methoxy tris-5,5-dimethyl-cyclohexen-2-one-3-yloxy silane can be made by effecting reaction in the presence of an acid acceptor between an alkanol, a halosilane and a 1,3-dicarbonyl cyclic organic compound, for example, 5,5-dimethyl-1,3-cyclohexane dione. The alkoxysilyl ethers are useful as vulcanizing agents for silanol terminated polydiorganosiloxanes.

A method for making an alkoxy-substituted 1,3-dicarbonylsilyl ether which comprises (1) effecting reaction between an aliphatic alcohol, an organohalosilane of the formula, (R).sub.a SiQ.sub.4-a and a 1,3-dione of the formula, ##STR14## in the presence of an acid acceptor and (2) recovering the resulting alkoxy-substituted 1,3-dicarbonylsilyl ether from step (1), where R is a C.sub.(1-13) monovalent organic radical, R 1 is selected from hydrogen, halogen and R, X and Y are divalent radicals selected from --O--, --S--, and ##STR15## Z is a divalent C.sub.(1-13) organic radical selected from alkylene, cycloalkylene, arylene and a fused ring structure, a is a whole number having a value of from 0 to 2 inclusive, b and c are equal to 0 or 1, R 3 is selected from hydrogen and R radicals, Q is a halogen radical.
