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
将两种异氰酸酯逐步加成到 N-三甲基锡烷基(二苯基亚甲基)胺中,Ph2C=NSnMe3,得到 3,4-dihydro-1,3-dialkyl-4,4-diphenyl-6-trimethylstannoxy-1,3,5-triazin-2 (1H)-一 (II) 通过 1/1 加合物和第二个异氰酸酯的极性 [4+2] 环加成。Ph2C=NSnMe3 的异硫氰酸酯加合物与异氰酸酯或异硫氰酸酯反应生成相应的连续插入产物 (IV)。
