ChemInform Abstract: 1,3,2‐Diazaphosphorinanes. Part 7. The Transamidation Method in the Synthesis of 1,3‐Dialkyl‐1,3,2‐diazaphosphorinanes.

Abstract

Transamidation of the diamidophosphite (II) with the propylenediamines (Ia) or (Ib) gives the diazaphosphorinanes (IIIa) and (IIIb).

Amides of Trivalent Phosphorus Acids as Phosphorylating Reagents for Proton-Donating Nucleophiles

“…540 The second line of research includes heterocyclizations. It has been shown for numerous examples that 1,2-, 541,542 1,3-, [543][544][545] and 1,4- [546][547][548][549][550] di-primary, primary-and-secondary, and di-secondary diamines are efficiently phosphorylated by phosphorus and phosphonous di-and triamides (Scheme 102).…”
