Abstract

Organophosphonic diamides of general formula [R1P (O)(NHR2) 2](1–8; R1= Ph, Cy or tBu and R2= Cy, iPr, tBu or Dipp) have been prepared by the addition of P, P'-dichloro (alkyl/aryl) phosphine oxide, R1P (O) Cl2, to a solution of primary amine in toluene. The synthesis of PhP (O)(NHtBu) 2 (1) in high yield was achieved by slow oxidation of PhP (NHtBu) 2 in air over several days. All new compounds have been characterized by ...
