Abstract

Polymer-supported reagents have experienced increasing popularity during the last twenty years (within chemistry). There are many advantages realized by binding a chemically reactive species to an insoluble support. Polymer-supported reagents have many applications in fields such as organic and inorganic chemistry, biochemistry and biology. A Fourier Transform Infrared (FTIR) study of the soluble analogues of polymer-supported reagents (synthesized in Dr. Alexandratos' laboratory) interacting with various target compounds was carried out. The complexation mechanisms displayed by the polymeric reagents were thus elucidated through model compound studies. Along these lines, the interaction of substituted anilines with polymeric phosphinic acid was investigated by FTIR studies of those anilines with phenyl phosphinic acid. The FTIR analysis shows that phenyl phosphinic acid is an intermediate compound between the strong methanesulfonic acid and the weak benzoic acid, when reacting with aniline. By analogy, polymeric sulfonic acid displays a stronger interaction with aniline than polymeric phosphinic acid. However, the latter resin provides a better understanding of substituent effects when reacting with substituted anilines.
