The synthesis of methyltrioctylsilane has been achieved in a single-step from commercially available trichloromethylsilane and trioctylaluminum. Co-products resulting from alkyl group redistribution are minimized by addition of sodium or lithium halides. Use of potassium or rubidium halides drastically changes the course of the reaction to produce methyldioctylsilane as the major product.
