Abstract
PURPOSE: To prepare the titled compound having linear-chain structure, useful as a starting material of synthetic chemicals, under mild conditions, without producing by-products, by reacting a sym-dialkoxytetramethyldisilane at a specific temperature in the presence of sodium methoxide without using a solvent.
CONSTITUTION: An α,ω-dialkoxypermethylpolysilane which is a straight-chain organopolysilane of formula RO[(CH3)2Si]nOR (n≥3) is prepared by reacting a sym-dialkoxytetramethyldisilane at -30W+70°C in the presence of sodium methoxide without using a solvent. There is no production of cyclinc polysilane by-product, and the reaction proceeds without using high temperature. As an alternative method, the objective compound can be prepared in an extremely short time, by carrying out the similar reaction in a solvent (e.g. diethyl ether, preferably, THF, etc.) within 10min, and immediately after the reaction, neutralizing the reaction mixture by adding the mixture usually to an aqueous solution of ammonium chloride, etc.
