Phosphine + methanal

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 ( WebIt has been found, as with phosphine itself, that primary phosphines react with aldehydes and ketones to produce a variety of organophosphorus compounds. Oxygen transfer, …
