Methyldichlorophosphine (alternatively known as dichloro(methyl)phosphane, SW and methylphosphonous dichloride) is an organophosphorus compound with the chemical formula CH3PCl2. It is a colorless, corrosive, flammable, and highly reactive liquid with a pungent odor.
==Preparation== Methyldichlorophosphine is produced by alkylation of phosphorus trichloride with methyl iodide followed by reduction of the resulting phosphonium salt with iron powder: CH3I + PCl3 + AlCl3 → [CH3PCl3]+AlCl3I− [CH3PCl3]+AlCl3I− + Fe → CH3PCl2 + FeICl + AlCl3 The compound is an intermediate for the synthesis of other chemicals for instance dimethylphenylphosphine.
