Abstract: | Reaction of VOCl3 with 2‐phenoxyethanol in n‐hexane in a 1:1 fashion gives dichlorooxo(2‐phenoxyethanolato)vanadium(V). HCl elimination yields the orange vanadium(V) complex, which is the first structurally characterized dichlorooxovanadium(V) alkoxide. The structure analysis reveals an unexpected tetrahedral coordination around the vanadium atom in the monomeric compound. Alcoholysis and hydrolysis reactions of [VOCl2(OCH2CH2OPh)] are monitored by 51V NMR spectroscopy. Activated with Me3SiCH2MgCl or nBu2Mg the complex catalyses the polymerisation of styrene. |
