ABSTRACT:
A method for preparing organosilicon compounds comprises: 1) converting the Si-bonded alkoxy in an Si-bonded alkoxy-functional organosilicon compound to the diorganosilyl group by reacting the Si-bonded alkoxy-functional organosilicon compound with organodisiloxane with the general formula HR.sub.2 Si--O--SiR.sub.2 H, where R is a monovalent hydrocarbyl group of 1 to 10 carbon atoms, in alcohol-containing acidic aqueous solution; and subsequently 2) treating with a sulfonic acid catalyst and carboxylic acid. This method is able to convert all the alkoxy groups in the alkoxy-functional organosilicon compound to diorganosilyl. This method can be used to synthesize a high-purity carbosiloxane dendrimer having a narrow molecular weight distribution.
