Tetraalkyldiphosphine imides and the isomeric diphosphazanes
The P 31 NMR-spectral data of diphosphine imides (I), diphosphazanes (II), and dialkylphosphinous amides (III) are shown. It is shown that for (I) with isopropyl groups on the 3-coordinate phosphorus atom two simultaneous processes may occur: the catalytic isomerization of the imides (I) into the diphosphazanes (II), and noncatalytic decomposition by a scheme. It is shown that the kinetically controlled reactions of dialkylphosphinous chloride with phosphinous amides and their salts lead to imides of the type R/sub 2/P (=NX)-PR/sub 2/, which are thermodynamically stable when X is an acceptor substituent, but when X - H, Alk, and Ar they are irreversibly isomerized into the diphosphazanes R/sub 2/P-NX-PR/sub 2/ under the action of electrophilic and nucleophilic catalysts.
