Ph2PCOONa 2, prepared from Ph2PNa and CO2, is readily hydrolyzed in protic media with formation of Ph2PH and CO2.Hydrolysis is much slower in NaOH and small quantities of Ph2P(O)O- and HCOO- are additionally formed.Reactions of 2 with RI in stoichiometrical amounts gave tertiary phosphines Ph2PR (R=Me, Et) while the phosphonium compound I resulted from 2 and MeI in excess.Ph2PCOOMe, Ph2PCOOSiMe3 or Ph2PCSSNa were obtained from 2 and (MeO)2SO2, Me3SiCl or CS2.Ph2P(O)ONa and Ph2P(S)SNa were isolated when 2 was reacted with O2 or S8 in benzene.
