Enantioselective radical cross-coupling reactions of silyl enol ethers using chiral oxovanadium
Kurihara, Masaaki,Hayashi, Taeko,Miyata, Naoki
, p. 1324 - 1325 (2001)
Asymmetric induction was observed in radical cross-coupling reactions of silyl enol ethers using chiral oxovanadium generated in situ from 8-phenylmenthol and vanadium oxytrichloride in the presence of MS4A (molecular sieves-4A).
Oxo- and imido-alkoxide vanadium complexes as precatalysts for the guanylation of aromatic amines

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
High valence vanadium complex promoted selective rearrangement of epoxides to aldehydes or ketones
Martinez, Fernando,Campo, Carmen del,Llama, Emilio F.
, p. 1749 - 1752 (2008/10/08)
High valence vanadium complexes induce the selective ring opening of epoxides. The monosubstituted epoxides are isomerized with complete regioselectivity each forming a single carbonyl compound exclusively. Likewise a highly regioselective isomerization of 1,1-disubstituted or 1,1,2-trisubstituted epoxides was observed in all reactions.
Oxovanadium(V)-Induced Ring-Opening Oxygenation of Cyclic Ketones in Alcohol
Hirao, Toshikazu,Mori, Makoto,Ohshiro, Yoshiki
, p. 2399 - 2400 (2007/10/02)
Cyclic ketones underwent ring-opening oxygenation on treatment with VO(OEt)Cl2 in alcohol under oxygen to give the corresponding keto ester or diesters depending on the substituent at 2-position.This system was applicable to a catalytic reaction.
