Abstract

See full text

A series of silicon compounds are provided, which are excellent precursors to small carbosilanes, such as 1,3,5-trisilapentane, 2,4,6-trisilaheptane, tris(silylmethyl)silane and tetrakis(silylmethyl)silane. A method of preparing a carbosilane involves forming a Grignard, lithium, or metallic reagent from a halomethyltrialkoxysilane, reacting the Grignard, lithium, or metallic reagent with a dihalodihydridosilane, a trihalohydridosilane, a tetrahalosilane, a dialkoxydihydridosilane, a trialkoxyhydridosilane, or a tetraalkoxysilane to yield a carbosilane precursor, and reducing the precursor to form the carbosilane.
