Electrosynthesis of heteroatom bonds. 5. Direct cross-coupling of dialkylphosphites with amines by an iodonium ion-promoted electrolytic procedure
An efficient direct cross-coupling procedure of dialkylphosphites with amines by an iodonium ion-promoted electrolysis, givin N-substituted dialkyl phosphoramidates, has been proposed.
REACTION OF SULFENAMIDES WITH DI-ALKYL AND TRIALKYL PHOSPHITES. AN EFFICIENT SYNTHESIS OF PHOSPHORAMIDATES BY UNUSUAL SUBSTITUTION AT S-N BOND IN (2-BENZOTHIAZOLYL)SULFENAMIDES
Regioselective attack of the trivalent phosphorus atom of dialkyl and trialkyl phosphites on either nitrogen or sulfur atom of sulfenamides has been found.The reaction of phenylsulfenamides with dialkyl phosphites yielded phosphorothiolates, whereas the treatment of (2-benzothiazolyl)sulfenamides with dialkyl and trialkyl phosphites gave phosphoramidates in excellent yields.
