Six borabenzene derivatives of vanadium are described. Reaction of the alkali metal borinates M(C5H5BR) (M = Na, K; R = Me, Ph) with VCl3 yields the paramagnetic, sandwich complexes V(C5H5BR)2. Reaction with HgCl2 and [Na{O(CH2CH2OCH3)2}2][V(CO)6] affords the tetracarbonyl compounds V(CO)4(C5H5BR). Upon heating in cycloheptatriene, the latter compounds produce the paramagnetic cycloheptatrienyl complexes V(C5H5BR)(C7H7) with sandwich structures. An X-ray structural study of V(CO)4(C5H5BMe) shows that the V(CO)4 fragment in the crystal is rotated by 10.4° relative to an ideal, eclipsed conformation where two CO groups are present in the plane through the B, V and C(4) atoms.
