Abstract : The direct analogs of the methyl silicones can be prepared by reaction of dimethyldichlorosilane with ammonia. The products of the reaction are mainly the trimer and tetramer with various amounts of polymeric material remaining as a distilllation residue. The products of this reaction display a tendency of silicon nitrogen systems--that of forming small rings instead of polymers. The practical utility of silicon-nitrogen polymeric systems is limited by the tendency of the Si-N bond to hydrolize forming the corresponding siloxanes. This tendency can be reduced by placing large substituents on silicon, thus partially sterically blocking the lone pair of electrons on nitrogen in Lewis base reactions with proton donating reagents which will cleave the Si-N bond. The present investigation is concerned with an attempt to tie up the lone pair of electrons on nitrogen by coordination with metallic ions. (Author)
