tungsten—carbene bond to give pentacarbonyl[diphenylmethyleneamino(organyloxy)carbene]tungsten or pentacarbonyl[alkylthio(diphenylmethyleneamino)carbene]tungsten complexes, respectively. Apart from these insertion products, other complexes are obtained which correspond to formal substitution of the carbene ligand by ROCN or R′SCN. The new carbene complexes are characterized analytically and spectroscopically
五羰基(二苯基卡宾)
钨分别与有机基
氰酸酯ROCN(R = Ph,Et,Pr i)或烷基
硫氰酸酯R'SCN(R'= Me,Et,Pr i)反应,插入CN在
钨-卡宾键上分别形成五羰基[二苯基亚甲基
氨基(有机基氧基)卡宾]
钨或五羰基[烷
硫基(二苯基亚甲基
