Phosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula PH3, classed as a pnictogen hydride. Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like rotting fish, due to the presence of substituted phosphine and diphosphane (P2H4). With traces of P2H4 present, PH3 is spontaneously flammable in air ( WebPrimary phosphines react with aldehydes and ketones to produce a variety of organophosphorus compounds [118]. Oxygen-transfer reaction is observed thus providing a new rout to secondary and tertiary phosphine oxides. Primary phosphines react with ketones and aromatic aldehydes in concentrated hydrochloric acid. Type of the reaction products …
