Notes:
Numerous areneselenenamides derived from ammonia, primary and secondary amines and two N,N-bis(arylseleno)alkylamines have been studied. The selenenamides bearing an electron-withdrawing substituent on the aromatic moiety are stable. The 1H, 13C and 77Se chemical shifts and some coupling constants are reported.For N.N-dialkyl-o-nitrobenzeneselenenamides, the 77Se NMR and the 17O NMR give evidence of an Se-O interaction. In N-alkyl derivatives, a hydrogen bond between the amine group and the ortho-substituent is proposed to explain the deshielding of the selenium nucleus.
