A method is provided for preparing sulfur-containing silane coupling agents by reacting an alkoxysilane acetal with a sulfurating agent. The sulfur-containing silane coupling agents so prepared include certain novel mercapto silanes, and are useful in providing rubber tires with improved properties.
