Method for preparation of tertiary-hydrocarbylsilyl compounds

摘要

A method for the preparation of tert-hydrocarbylsilyl compounds is new. - The method comprises reacting a mixture of diethylene glycol dibutyl ether and a Grignard reagent of formula RMgX with a silicon compound of formula R1aSiX4-a in the presence of a copper catalyst. R = 4-25C tert-hydrocarbyl group; R1 = optionally substituted monovalent 1-20C hydrocarbon group; X = halo; a = 0 to 3. Further claimed is a method comprising reacting magnesium metal with a mixture of diethylene glycol dibutyl ether, a Grignard reagent of formula RMgX with a silicon compound of formula R1aSiX4-a in the presence of a copper catalyst.
