Abstract
We previously showed that the reaction of chloro(chloromethyl)dimethylsilane with bis(N-methyl-N-trimethylsilylamido)methylphosphonate is accompanied by separation of 2 equiv of chlorotrimethylsilane and provides 1,2,3,4,4-pentamethyl-1,3-diaza-2-phospha4-silolidin-2-one [1]. With the purpose of investigate the possibility of formation of new silacyclanes on the basis of chloromethyl derivatives of silicon we turned to reaction of N,N -bis(trimethylsilyl)-N-methylN -phenylurea (Ia) and N,N -bis(trimethylsilyl)N-methyl-N -p-chlorophenylurea (Ib) with chloro(chloromethyl)dimethylsilane. Silylated urea Ib was prepared from heptamethyldisilazane and p-chlorophenyl isocyanate.
