A liquid phase selective oxidation process is described. The process involves the partial oxidation of alkanes to partially oxidized products. A lower alkane, a solvent, and a soluble metal catalyst are contacted in the presence of an oxidizing agent in a reaction zone under partial oxidation conditions to produce the partially oxidized products. The partially oxidized products include one or more of lower alkyl alcohols, lower alkyl ketones, and lower alkyl acetates. The soluble metal catalyst is a soluble metal salt of cobalt, manganese, chromium, titanium, copper, nickel, vanadium, iron, molybdenum, tin, cerium, zirconium, or combinations thereof, and the promoter comprises a bromine source, an imide source, or combinations thereof.
