A Direct Catalytic Synthesis of Sodium Diarylphosphinates and Their Corresponding Acids from Sodium Phosphinate

In this contribution we present the direct conversion of sodium phosphinate (NaH2PO2·H2O) to symmetrical sodium diarylphosphinates and their corresponding acids by using palladium catalysis. This route eliminates the need for chlorinated precursors, such as PCl3and intermediate alkyl- or ammoniumphosphinates.

ZUR KENNTNIS DES NATRIUMDIPHENYLPHOSPHINOFORMIATS Ph2PCOONa

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.

Preparation of anhydrous organic acid salts

One-step process for preparing anhydrous, organic acid alkali or alkaline earth metal salts by contacting and reacting an organic or polymeric acid fluoride, anhydride or ester and an organic alkali or alkaline earth metal silanolate.
