Spectrophotometric studies on the charge transfer complexes between molecular iodine and some pentaatomic rings containing the selenoamido entity, ie X· CH 2· CH 2· NR· C= Se (where for R= H, X= CH2, NH, NMe, NEt, S; for R= Me, X= NMe, S; for R= Et, X= NEt) have been carried out in CCl4 and CH2Cl2 solutions. The presence of isosbestic points are indicative of 1: 1 molecular adducts. The simultaneous determination of the stability ...
