Claim:
A one-pot process for reducing a sulfur- or nitrogen-containing compound and producing an oxygenate in a hydrocarbon substrate, which comprises the steps of: (a) placing a homogeneous catalyst in a reactor; (b) adding the hydrocarbon substrate in the reactor; and (c) introducing an oxidant into the reactor wherein the oxidant is selected from the group consisting of an O 2 /CO 2 mixture, an O 2 /CO 2 /He mixture, and O 2 /CO 2 /Ar mixture, in which the O 2 /CO 2 mixture comprises 7-80 vol % CO 2 , wherein the homogeneous catalyst is M n+ /a first solvent or M n+ /a second solvent/Mm + /a third solvent or a mixture thereof; the M n+ is selected from the group consisting of Co 3+ , Mo 6+ , MoO 2 2+ , MoO 4 +, MoO 4 2−, V 5+ , VO 3+ , VO 2 3+ , W 6+ , WO 4 2− , Cr 3+ , Ti 4+ , Fe 3+ , Ni 2+ , Zr 4+ , ZrO 2+ , Hf 4+ , Ta 6+ , Nb 5+ , Ce 4+ and Ce 3+ ; the M 1 n+ is selected from the group consisting of Co 3+ , Mo 6+ , MoO 2 2+ , MoO 4+ and MoO 4 2− ; the M 2 m+ is selected from the group consisting of Co 3+ , Fe 3+ , Ni 2+ , Cu 2+ , V 5+ , VO 3+ ,VO 2 3+ , Cr 3+ , Ti 4+ , Zr 4+ , ZrO 2+ , Hf 4+ , Ta 6+ , Nb 5+ , Re 4+ , Ru 4+ , Sm 4+ , Pr 3+ and Ce 3+ ; the first solvent, the second solvent and the third solvent are the same or different and each is independently selected from the group consisting of water, alcohols, CH 3 CN, DMF, N-pyrrolodone, formic acid, acetic acid, octanoic acid, trifluoroacetic acid, acetic acid-water mixture, aliphatic or aromatic C 6 -C 16 hydrocarbon, H-donor solvent, diesel oil, gasoline, LCO, and a mixture thereof.
