Cyclopentadienylirontellurophosphorane cations [Fe(C5H5)(CO)2(TePR3)]+(5; R = Me, Pri, But, NMe2, or morpholino) have been prepared by reaction of [Fe(C5H5)(CO)2(thf)]+(thf = C4H8O) with TePR3. The bonding properties of the Fe–Te–P fragment are discussed using n.m.r. data which indicate π bonding between the iron and tellurium atoms.
环戊二烯基铁碲磷正离子[Fe(C 5 H 5)(CO)2(TePR 3)] +(5 ; R = Me,Pr i,Bu t,NMe 2或吗啉代)已通过[Fe(C 5 H 5)(CO)2(thf)] +(thf = C 4 H 8 O)和TePR 3。使用nmr数据讨论了Fe–Te–P片段的键合性质,该数据表明铁原子与碲原子之间存在π键。
