imidovanadium(III) complexes [tBuN=VCp(PR3)2], [tBuN=VCpP(OR)3}2] and [tBuN= VCp(CO)2] have been prepared starting from tBuN=VCpCl2 by reductive dehalogenation with magnesium. The reaction of [tBuN=VCp(PMe3)2] (2a) with carbon monoxide, alkynes, alkenes, tert-butylphosphaalkyne, nitriles, ketones and carbon disulfide furnished the complexes [tBuN=VCp(PMe3) (L)], while the vanadium(V) compound tBuN=VCp(O2C2Ph2) is
亚胺钒(III)配合物[tBuN=VCp(PR3)2]、[tBuN=VCpP(OR)3}2]和[tBuN=VCp(CO)2]已从tBuN=VCpCl2开始通过还原脱卤制备用镁。[tBuN=VCp(PMe3)2] (2a) 与一氧化碳、炔烃、烯烃、叔丁基磷炔、腈、酮和二硫化碳的反应提供了复合物 [tBuN=VCp(PMe3) (L)],而钒(V)化合物tBuN=VCp(O2C2Ph2)与苄基形成。获得的所有钒 (III) 配合物都是抗磁性的(d2,低自旋构型),并且已经通过光谱方法(MS;1H、13C、31P、51V NMR)进行了表征。
