- PROCESS FOR SELECTIVE PRODUCTION OF HALOSILANES FROM SILICON-CONTAINING TERNARY INTERMETALLIC COMPOUNDS
-
A process includes contacting an organohalide with a ternary intermetallic compound at a temperature of 300 °C to 700 °C to form a reaction product including a halosilane. The ternary intermetallic compound includes three metals. The first metal is Cu or Mg; the second metal is Au, Ni, or Pd; and the third metal is Si.

- ALTERNATIVE METHODS FOR THE SYNTHESIS OF ORGANOSILICON COMPOUND
-
A method of forming chloro-substituted silanes from the reaction of an alkoxysilane with a chlorinating agent in the optional presence of a catalyst is provided. More specifically, chloro-substituted silanes, including but not limited to silicon tetrachloride, are formed by reacting a chlorinating agent, such as thionyl chloride, with an alkylalkoxysilane having the formula (R'0)4-xSiRx, where R and R' are independently selected alkyl groups comprising one or more carbon atoms and x is 0, 1, 2, or 3. The catalyst may be dimethylformamide, (chloromethylene)dimethyliminium chloride, or triethylamine, among others. The chloro- substituted silane formed in the reaction along with several by-products has the formula (RO)4-x-ySiRxCly; where x is 0, 1, 2, or 3 and y is 1, 2, 3, or 4. One of the by-products of the reaction is an alkyl chloride.

- Alternative methods for the synthesis of organosilicon compounds

A method of forming chloro-substituted silanes from the reaction of an alkoxy-or acetoxy-substituted silane with a chlorinating agent in the optional presence of a catalyst is provided. For instance, chloro-substituted silanes, including but not limited to silicon tetrachloride, are formed by reacting a chlorinating agent, such as thionyl chloride, with an alkoxysilane having the formula (R'O)4-xSiRx, where R and R' are independently selected alkyl groups comprising one or more carbon atoms and x is 0, 1, 2, or 3. The catalyst may be dimethylformamide, (chloromethylene)dimethyliminium chloride, or triethylamine, among others. The chloro-substituted silane formed in the reaction along with several by-products has the formula (R'O)4-x-ySiRxCly; where x is 0, 1, 2, or 3 and y is 1, 2, 3, or 4. One of the by-products of the reaction is an alkyl chloride.
