Abstract

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%.
