Abstract

Nucleophilic addition of a copper-phosphazene anion [(NPCl2)2NPR]2Cu (R = alkyl) to an aldehyde or ketone, followed by acid hydrolysis, leads to the formation of geminal alkyl(hydroxy-alkyl) derivatives in reasonable to high yields.

Isocyanato cyclophosphazenes provide another entrance to organo-substituted derivatives, in which (NPCl2)2 NPNH2 NCO appears to be a versatile starting material. Interesting differences are observed between the reactions of (NPCl2)3 with alkali cyanates and silver cyanate in the presence of an alcohol, using acetonitrile as a solvent.
