Reaction of trimethylsilyl sulphide with phenyl isocyanate gives a 1 : 1 insertion product, but subsequent insertion of phenyl isocyanate takes place readily in the case of trialkylstannyl sulphide, to produce triphenyl isocyanurate. When chloral is used as a reactant for trialkyltin sulphides, substitution of all three chlorine atoms occurs, to afford trialkyltin chloride and (RS)3C·CHO, although

硫醚与
异氰酸苯酯的反应生成1:1的插入产物,但是在三烷基
锡烷基
硫醚的情况下,
异氰酸苯酯的随后插入很容易发生,从而生成异

氯醛用作三烷基
锡硫化物的反应物时,尽管在三烷基甲
硅烷基
硫化物的情况下获得了简单的插入产物,但所有三个
氯原子都被取代,从而得到三烷基
