[NaO(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
描述了六种钒的硼苯衍生物。碱金属硼酸酯盐M(C 5 H 5 BR)(M = Na,K; R = Me,Ph)与VCl 3的反应产生顺磁性夹心复合物V(C 5 H 5 BR)2。与HgCl 2和[Na O(CH 2 CH 2 OCH 3)2 } 2 ] [V(CO)6 ]反应,得到四羰基化合物V(CO)4(C 5 H 5 BR)。在环庚三烯中加热后,后者化合物生成顺磁性环庚三烯基络合物V(C 5H 5 BR)(C 7 H 7)具有三明治结构。对V(CO)4(C 5 H 5 BMe)的X射线结构研究表明,晶体中的V(CO)4片段相对于理想的偏光构象旋转了10.4°,在该构想中,两个CO基团存在通过B,V和C(4)原子的平面。
