The S-methylation of N-(trimethylsilylmethyl)thioureas and the subsequent desilylation of the silylmethyl group generates N-unsubstituted azomethine ylides having both methylthio and amino groups at the ylide carbon. These azomethine ylides undergo succes
N-(TRIMETHYLSILYLMETHYL)CARBODIIMIDES AND -KETENIMINE AS PRECURSORS OF IMINO- AND ALKYLIDENE-2-AZAALLYL ANIONS

The fluoride-induced desilylation of N-(trimethylsilylmethyl)carbodiimides and -ketenimine generates imino- and alkylidene-2-azaallyl anions which cycloadd to a variety of aldehydes giving regioisomeric 1,3-oxazolidines as cycloadducts.
