Cage organometallosiloxanes were synthesized according to a new procedure using monomeric organoalkoxysilanes as the starting
compounds. The latter were subjected to hydrolysis immediately before the exchange reaction of sodium silanolate with metal
halides. Difficultly accessible metallovinylsiloxanes, metallomethylsiloxanes, and metallosiloxanes containing a functional
group in the organic radical at the silicon atom can be readily prepared according to the method proposed.

The reactions of cage-like copper/sodium organosiloxanes with CuCl2 were studied. Cage-like copper organosiloxanes containing the Si—O—Cu—Cl group were synthesized for the first time. 相似文献

Condensation of acetylacetone with carbamide in nonpolar media (benzene, toluene) is initiated by organochlorosilanes. The reaction rapidly occurs under mild conditions to give oligosiloxanes and 4,6-dimethylpyrimidin-2(1H)-one hydrochloride. The conversion of chlorosilanes and the yields of oligosiloxanes are nearly ~100%. 相似文献

The reactions of [(2-acetoxyetoxy)methyl]dimethylchlorosilane and 1-acetoxy-2-(dimethylchlorosilylmethoxy)benzene with the cage phenylcopper and phenylmanganese siloxanes leads to the cleavage of the M—O—Si bond to give metal chlorides and six-unit cyclosiloxanes with an acetoxy group in the organic substituent at the silicon atom. Methanolysis of these acetoxy derivatives does not affect the ring structure and affords the corresponding polyhydric alcohols. 相似文献
