Abstract
When the di-aryl or di-alkyl phenyl phosphonamide (RNH)2P(O)Ph 1 is tr eated with sulfur(I) chloride (S2Cl2) in base,the product is an unexpe cted, unusual seven-membered diazatetrathiaphospha heterocycle 3; the X-ray structure and NMR spectra of these two unique heterocycles indic ate that they exist in a pseudo-chair conformation with steric congest ion limiting the freedom of rotation of the phenyl group; and represen t the first known examples of this hetero-ring system.
