Synthesis of (arylimido)vanadium complexes and their application for oxidative coupling reactions of silyl enol ether derivatives

(Arylimido)vanadium(v) complexes, V(NAr)(OEt)Cl2 [Ar = C 6H5, p-BrC6H4, p-(MeO)C 6H4] or V(NAr)Cl3 [Ar = o-BrC6H 4, o-(MeO)C6H4] were synthesized by the reaction of VO(OEt)Cl2 or VOCl3, respectively, with the corresponding aryl isocyanates. X-Ray crystal structure determination for V(NAr)(OEt)Cl2 (Ar = C6H5 and p-BrC 6H4) elucidates the alkoxido-bridged dimeric building blocks [V(NAr)(OEt)Cl2]2, wherein the substituent on the benzene ring was found to affect the character of the imido nitrogen. The 51V NMR spectroscopic measurements indicated that the electronic state of the vanadium metal centre depends on the ligands connecting to the vanadium and the substituents on the benzene ring. The selective oxidative cross-coupling reaction of silyl ketene acetal with silyl enol ether was achieved using V(Np-BrC6H4)Cl3 or V(No-BrC 6H4)Cl3.

Oxovanadium-Induced Oxidative Desilylation for the Selective Synthesis of 1,4-Diketones

Silyl enol ethers underwent the VO(OR)Cl2-induced homo- or cross-coupling giving 1,4-diketones selectively via one-electron oxidative desilylation.
