mixture of the new compounds (π-C5H5)2Ti(C6F5)2 and (π-C5H5)2Ti(C6F5)Cl. Both of these complexes are significantly more robust than analogous aryltitanium compounds containing carbon-titanium σ-bonds. Pyrolysis of (π-C5H5)2Ti(C6F5)2 at 150° affords small quantities of (π-C5H5)2Ti(C6F5)F, which is best prepared by treating (π-C5H5)2Ti(C6F5)2 with hydrofluoric acid. The pentafluorophenyl groups are cleaved
二处理(π -环戊二烯基)二氯化钛与pentafluorophenyllithium,得到新的化合物的混合物(π-C 5 H ^ 5)2的Ti(C 6 ˚F 5)2和(π-C 5 H ^ 5)2的Ti(C 6 F 5)Cl。这两种配合物都比含碳-钛σ-键的类似芳基钛化合物坚固得多。的(π-C热解5 ħ 5)2的Ti(C 6 ˚F 5)2在150℃,得到少量的(π-C的5 ħ5)2的Ti(C 6 ˚F 5)F,这是最好的治疗(π-C制备5 ħ 5)2的Ti(C 6 ˚F 5)2用氢氟酸。五氟苯基被氯化氢从五氟苯基钛化合物上裂解为五氟苯。化合物(π-C 5 H ^ 5)2的Ti(C 6 ˚F 5)OH和(π-C 5 H ^ 5)2的Ti(C 6 ˚F 5)OC 2 H ^ 5已经从(π-C制备5 ħ 5)2的Ti(C 6 ˚F 5)氯,分别通过水解和醇解。
