Abstract: The present invention is a process for reducing the number of halogens on organohalosilanes and volatile organohalopolysilanes, while preventing unwanted reactions. The process takes advantage of the high susceptibility of the silicon-halogen bond to chemical reduction by an alkylaluminum hydride. This susceptibility allows the halogen to be quickly removed from the organohalosilane, forming reduced product, before less favorable reactions can occur. The reduced product is immediately removed from the reaction mixture by vacuum distillation, preventing further reactions. The process may be used to remove one or more, or all, of the halogens from organohalosilanes and volatile organohalopolysilanes.

Abstract: The present invention is a process for reducing the content of halogen bound to the silicon atom of halosilacycloalkanes. The process employs an alkylaluminum hydride as a reducing agent. Alkylaluminum hydrides have been found to be highly effective in removing the halogen bound to silicon, with lessor affect on the reactive silacycloalkane ring. In another embodiment of the present invention, the halosilacycloalkane is added beneath the surface of an excess of liquid alkylaluminum hydride. The temperature and the pressure of the reaction are maintained such that the resultant silacycloalkane products are immediately vaporized and removed from the reaction vessel. This minimizes further reaction of products and improves the yield of desired product.
