摘要：

Kinetically stable, four-coordinate vanadium (IV) neopentylidene complexes such as [(Nacnac)V=CHtBu(thf)](BPh4) (Nacnac-=[Ar]NC(Me) CHC(Me)N[Ar], Ar=2,6-(CHMe2)2C6H3), which was prepared by oxidatively induced α-hydrogen abstraction from [(Nacnac)V(CH2tBu)2] with AgBPh4 in THF (see structure), contain the shortest V=C bonds known to date.
