Abstract
We have developed two new amino ligands [N,N’-cyclohexyl –(2,6-diisopropylphenyl) amino Lithium] and [N,N’-cyclohexyl –(2,4,6-trimethylphenyl) amino Lithium] reacting with VCl3(thf)3 to get two masked three coordinate complex: Complex 1 [VCl(THF)(N(Cy)dipp)2] and Complex 2 [VCl (THF)(N(Cy)dipp)2].To this bulkyl Complex 1,treat with N2C(H)TMS or N3R (R=Mes,TMS),we can get three organo imido vanadium complex product Complex 3 [(TMS-C(H)N2)VCl(THF)(N(Cy) dipp)2], Complex 4 [(Mes-N3)VCl(THF)(N(Cy)dipp)2],and Complex 5 [(TMS-N)VCl(THF)(N(Cy)dipp)2].We also treat a n-Butyl lithium deprotonating trimethylsilyldiazomethane with Complex 1 to get an unexpected product Complex 5 which lose a lithium cyanide and its side product Complex 6 [V(N(Cy)dipp)2 (CN)2Li(OEt)2]2 proving the formation of LiCN. So we can suppose the possible reaction way. In the other way, Complex 1 react with NaN3 affords a nitrido vanadium complex Complex 7 [V(N(Cy)dipp)2(μ-Cl)(μ-N) Na(OEt2)2]. We can get a similar result, Complex 8 [VCl(N(Cy) dipp)2(N-C(O)tBu)2] and Complex 9 [VCl(N(Cy)dipp)2(N-C(O)Ph)2] if we treat Complex 7 with pivaloyl chloride or benzoyl chloride.
