Abstract
Stepwise addition of two isocyanates to N-trimethylstannyl(diphenylmethylene)amine, Ph2C=NSnMe3, gives 3,4-dihydro-1,3-dialkyl-4,4-diphenyl-6-trimethylstannoxy-1,3,5-triazin-2(1H)-one (II) by a polar [4+2] cycloaddition of the 1/1 adduct and the second isocyanate. The isothiocyanate adducts of Ph2C=NSnMe3 react with either isocyanates or isothiocyanates to yield the corresponding consecutive insertion products (IV).
