compound C5H5ZrCl3, C5H5ZrBr3 and C5H5ZrI3 and the reported compound C5H5TiCl3 have been made by the novel reaction of cyclopentadiene vapour with the metal trihalides. The known compounds (C5H5)2ZrCl2 and (C5H5)2ZrBr2 were made similarly from the dihalides. Solution methods were used also to make C5H5ZrCl3, C5H5ZrBr3 and (C5H5)2ZrI2, previously uncharacterized, and an improved characterization of C5H5TiCl3
化合物C 5 H 5 ZrCl 3,C 5 H 5 ZrBr 3和C 5 H 5 ZrI 3和所报道的化合物C 5 H 5 TiCl 3是通过
环戊二烯蒸气与
金属三卤化物的新颖反应制得的。由二卤化物类似地制备已知化合物(C 5 H 5)2 ZrCl 2和(C 5 H 5)2 ZrBr 2。还使用溶液法制备C 5以前未表征的H 5 ZrCl 3,C 5 H 5 ZrBr 3和(C 5 H 5)2 ZrI 2,并且已经改善了C 5 H 5 TiCl 3的表征。所有这些化合物均包含π键合的
环戊二烯基结构。
