Convenient methods for the synthesis of functionalized organophosphorus compounds containing carbonyl groups as well as di- or trialkoxymethyl fragments attached to phosphorus, and their derivatives, starting from the available derivatives of trivalent phosphorus acids, are proposed, and some properties of the new functionalized organophosphorus compounds are presented. So, the alkylation and acylation

A series of chlorinated dimethyl tetrafluorodiazadiphosphetidines, [RF2PNMe]2, where R = ClCH2(I), Cl2HC (II), or Cl3C (III) have been studied. The syntheses of the two new members of this series, (II) and (III), are described. Analyses of the 31P-1H} and 19F-1H} noise-decoupled n.m.r. spectra yielded values for chemical shifts and coupling constants. In addition some 1H n.m.r. data are given, including
