Interaction of [V(NR)Cl3] compounds with 1,2-dimethoxyethane (dme) afforded [V(NR)Cl3(dme)] (R = 2,6-iPr2C6H3 1a or 1-adamantyl 1b) complexes in a nearly quantitative yield. Compounds 1 are suitable sources for the synthesis of other d0 imidovanadium complexes. Metathesis reactions of 1 with the sodium salt of the Klaeui's ligand, NaLOEt (LOEt = (H-C5H3)Co{P(O)(OEt)2}3), yielded complexes [V(NR)Cl2(LOEt)] (R = 2,6-iPr2C6H3 2a or 1-adamantyl 2b). Treatment of 1 with several bidentate monoanionic dithio-ligands, -S2CR′, gave the corresponding imido complexes of general formulation [V(NR)(S2CR′)3] (for R = 2,6-iPr2C6H3; R′ = NC4H4 3a, NiPr2 4, OiPr 5a or SiPr 6a; for R = 1-adamantyl; R′ = NC4H4 3b, OiPr 5b or SiPr 6b). The molecular structure of [V(2,6-iPr2C6H3N)(S 2CNC4H4)3] 3a has been determined by an X-ray study. Finally, the reaction of 1a with Na(acac), in a 1:2 molar ratio, produces complex [V(2,6-iPr2C6H3N)Cl(acac) 2] 7. Copyright 1999 by the Royal Society of Chemistry.
