The direct nitrogenation of alkenes and functionalized dienes having hydroxy or carbonyl groups was examined by using oxophilic early transition metal complexes. The vanadium(V) oxytriisopropoxide VO(OiPr)3 has been examined as catalyst for nitroso ene reaction and nitroso Diels-Alder reaction. The nitrosocarbonyl intermediates can be efficiently generated by the oxidation of hydroxamic acids with V(V) catalyst (1mol%) without any other oxygenated by-products. The conjugated dieneshaving carbonyl group were converted to the nitroso Diels-Alder adducts in good yieldswith high regioelectivity.
