Abstract
Bissilylamino group-bearing chlorosilane compounds of formula (1):[(CH3)3Si]2NCH2CH2CH2Si(CH3)nCl3−n (1)wherein n is 0 or 1 are novel. They are useful as silane coupling agents and surface treating agents. They can be readily converted, through reaction with alcohols, to bissilyl group-bearing alkoxysilane compounds which are useful as intermediates for the synthesis of aminopropyl-modified silicone oil. The invention also provides an industrially advantageous method capable of preparing the bissilylamino group-bearing chlorosilane compounds.
