Hydrogen Bonding of Anilines: Experimental and Theoretical Studies of Complexes of Various Compositions

Review of works on studies of the influence of the position, number and a kind of substituents in phenyl ring of aniline on proton donor ability in hydrogen bond, spectral, geometric, electrooptic and force characteristics of amino group in complexes with different proton acceptors of 1:1 and 1:2 composition in intra- and intermolecular hydrogen bonds is presented. The influence of proton donors and proton acceptors on the kind of correlation between spectral, geometric, force and electrooptic characteristics of the amino group is analyzed. Obtained results demonstrate the possibility of quantitative description of the changes of dynamic, geometric, force and electrooptic properties of amino group in substituted anilines on passing from free molecules to bonded ones and extend the understanding of the role of various factors in the process of molecular aggregation.
