Abstract: A method of producing a phospholene oxide is disclosed. A dihalohydrocarbylphosphine, 2-methyl-1,3-butadiene, and a halogenated hydrocarbon solvent are combined to form an adduct via an addition reaction in a homogenous system wherein the ratio of the 2-methyl-1,3-butadiene to the dihalohydrocarbylphosphine is from 1.0 to 2.0 and wherein the solvent is present in an amount of greater than 200 mL per mole of dihalohydrocarbylphosphine. The adduct is combined with alcohol and a carbonate or with a solution of metal hydroxide and water to form the phospholene oxide.
