Abstract
Abstract Organofunctional-silicon hydrides having, in addition, a halo substituent are provided. These compounds, of generic formula: QSiYY'H, (1) where Q is an organofunctional alkyl radical, Y is a halide radical, and Y' is Y or a monovalent hydrocarbon radical free of aliphatic unsaturation, are useful as intermediates in the production of various bis-(organofunctional-alkyl)silanes. Additionally, they are useful as waterproofing agents for various materials.
