with polar fulvenes (Z2 = H, NMe2; (NMe2)2 and S(CH2)2S) gives the Fv complexes C5H4CZ2V(CO)3SnR3 with the stannyl ligand still coordinated to vanadium. A Fv complex, V(NO)(CO)2C5H4CHNMe2, is also obtained from the reaction of V(NO)(CO)5 with dimethylaminofulvene. The IR, 1H, 13C and 51V NMR data show that the dipolar (i.e. the h5-cyclopentadienyloidal) resonance structure predominates in all but the
配合物R 3 SnV(CO)5 PPh 3和R 3 SnV(CO)6(R = Ph,Et,n-Bu,CH 2 Ph)(描述了一种改进的合成方法)与五烯酮C 5 H 4反应CZ 2给出环取代的环戊二烯基(Cp)或富烯(Fv)配合物。极性较小的富勒烯形成烷基-Cp络合物(Z 2 = Ph 2和(对位取代的Ph)2)或烯基-Cp络合物(Z 2 = Me 2,(CH 2)4,(CH 2)5)消除了苯乙烯基配体,而与极性富勒烯(Z 2 = H,NMe 2 ;(NMe 2)2和S(CH 2)2 S)的反应产生了Fv络合物C 5 H 4 CZ 2 V( CO)3 SNR 3与配体甲锡烷基仍然配位钒。Fv络合物,V(NO)(CO)2 C 5 H 4 CHNMe 2,也可以从V(NO)(CO)5与二甲基氨基富勒烯的反应中获得。红外,1 H,13 C和511 H NMR数据表明偶极(即,h 5-环戊二烯基)共
