AN UNUSUAL REARRANGEMENT OF N-SUBSTITUTED THIOPHOSPHORYL CARBONYL MIXED IMIDES
DeBruin, Kenneth E.,Boros, Eric E.
, p. 1047 - 1050 (2007/10/02)
N-Substituted O,O-dimethyl N-benzoyl phosphoramidothioates (III, R=Me, Ph but not H) undergo an uncatalyzed unimolecular rearrangement in an inert solvent; whereby, the carbonyl oxygen atom exchanges position with the thiophosphoryl sulfur atom (an O,S Sw
