## Thermochemical and mechanistic aspects of tautomerization resulting from proton transfer in [2,2'-bipyridyl]-3,3'-diol have been investigated by ab initio computations. From a classical point of view, complete characterization of energy minima and first-order saddle points indicates that proton
The complexation behaviour of 2,2Ј-bipyridyl-3,3Ј-diol and 2,2Ј-bipyridyl-3-ol, BP(OH) 2 and BPOH, with various heavy and transition metal ions has been investigated in aqueous, alcoholic, and acetonitrile solutions. Whereas the complexes with paramagnetic ions and Hg II are non-fluorescent, Zn II a
