A method is useful for preparing alkylalkoxysilanes, such as alkylalkoxysilanes, particularly dimethyldimethoxysilane. The method includes heating at a temperature of 150&#xb0; C. to 400&#xb0; C., ingredients including an alkyl ether and carbon dioxide, and a source of silicon and catalyst. The carbon dioxide eliminates the need to add halogenated compounds during the method.

Method for preparing alkylalkoxysilanes

A method for making long chain hydroxyl terminated polydiorganosiloxanes with low cyclics content via condensation polymerization employs a selective catalyst. The catalyst includes a salt-anion complex and a free acid.

Method for condensation polymerization of hydroxyl-terminated polydiorganosiloxanes

A method for making long chain hydroxyl terminated polydiorganosiloxanes with low cyclics content via condensation polymerization employs a trifluoromethane sulfonate compound catalyst. The trifluoromethane sulfonate may be complexed with a multidentate ligand.
