Dimethylphosphine is the organophosphorus compound with the formula (CH3)2PH, often written Me2PH. It is a malodorous gas that condenses to a colorless liquid just below room temperature. Although it can be produced by methylation of phosphine, a more practical synthesis involves the reduction of tetramethyldiphosphine disulfide with tributylphosphine:
