Abstract

Vanadium oxo-alkoxide complexes [V (O)(Cl) 3− x (OR) x](x= 1, R= Me (1), Et (2), n-Pr (3); x= 2, R= Me (4), Et (5), n-Pr (6)) were obtained by a clean reaction between [V (O) Cl3] and different excesses of ROSiMe3 silicon ethers. Imido complexes [V (NAr)(Cl) 3− x (OR) x] 2 (Ar= 2, 6-i-Pr2C6H3; x= 1, R= Me (7), Et (8), n-Pr (9); x= 2, R= Me (10), Et (11), n-Pr (12)) were prepared in excellent yields by reaction of the oxo-alkoxide precursors and ArNCO. ...
