METHOXY-CATALYSED REARRANGEMENT OF N- TO O-(DIPHENYLPHOSPHINYL)HYDROXYLAMINE

In methanol Ph2P(O)NHOH undergoes rapid NaOMe-catalysed rearrangement to Ph2P(O)ONH2 which is subsequently converted into Ph2P(O)ONa and Ph2P(O)OMe.

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.

THE STEREOCHEMICALLY CONTROLLED HORNER-WITTIG ROUTE TO UNSATURATED ACIDS: THE BAEYER-VILLIGER REARRANGEMENT OF α-(1-Ph2PO-ALKYL)-CYCLOHEXANONES

Lithiated alkyl diphenylphosphine oxides attack cyclic epoxides with high stereoselectivity: Baeyer-Villiger rearrangement of the derived ketones gives Horner-Wittig intermediates for the synthesis of Z unsaturated acids
