Phosphine (IUPAC name: phosphane) is the compound with the chemical formula PH3. It is a colorless, flammable, toxic gas and is classified as a pnictogen hydride. Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like garlic or rotting fish, due to the presence of substituted phosphine and diphosphane (P2H4). With traces of P2H4 present, PH3 is spontaneously flammable in air (pyrophoric), burning with a luminous flame. Phosphines are also a group of organophosphorus compounds with the formula R3 (RP = organic derivative). Organophosphines are in catalysts where they are important to various complex metal ions; a chiral catalyze derived from phosphine?
