N2 - The reaction of [(MenacnacDipp)Mn(μ-Cl)]2(2) (MenacnacDipp = HC(C(Me)NDipp)2; Dipp = 2,6-Pri2C6H3) with sodium triethylborohydride in a toluene—THF mixture afforded the complex [(MenacnacDipp)Mn(μ-H)2BEt2(THF)] (3). The reaction of 2 with Na[HBEt3] in toluene under THF-free conditions gave a mixture of products. The set and the ratio of these products in the resulting crystalline mixture were established by quantitative powder X-ray diffraction analysis: [(MenacnacDipp)Mn(μ-H)]2(1), [(MenacnacDipp)−Mn(μ-H)2BEt2] (4), and unreacted compound 2 in the ratio of 15:4:1 and traces of an unknown crystalline phase. The reaction of [(MenacnacDipp)VCl2] (5) with Na[HBEt3] yielded the compound [(MenacnacDipp)V(μ-H)(μ,κ1:1−C:C′−C2H4)BEt2] (6) containing the unusual ligand [HBEt2(CH2CH2)]2−. The vanadium analog of compound 3, [(MenacnacDipp)V(μ-H)2BEt2(THF)] (7), was isolated in one experiment. Besides. a small amount of the complex [(MenacnacDipp)V(μ-H)BEt3(THF)] (8) was detected in the mixture of crystalline products. The structures of compounds 3, 4, 6, 7, and 8 were determined by single-crystal X-ray diffraction.
