The addition of PH3 to formaldehyde to give P(CH2OH)3 is catalysed by a range of platinum-(IV), -(II) and -(0) compounds including Na2[PtCl6], K2[PtCl4], [PtCl2P(CH2OH)3}2]2 and [PtP(CH2OH)3}4]·H2O 3. A large ratio of P(CH2OH)3 to Pt is present under the conditions in which the catalysis is operated and the hypothesis that a common platinum–P(CH2OH)3 complex is present under these conditions has
