The structural criteria of hydrolytic stability in series of dioxaborine polymethine dyes
چکیده انگلیسی

The structural criteria that affect stability to the alkaline hydrolysis of dioxaborine dyes were analyzed. Dyes with different electron-donor and electron-withdrawing groups conjugated with dioxaborine cycle, and also having some steric effects were analyzed. For this purpose, some new dioxaborine dyes were synthesized. It was shown that electron-donor substituents, unlike electron-withdrawing ones, increase the hydrolytic stability of the dioxaborine dyes. The possible way of the basic hydrolysis of dioxaborine dyes was suggested. The products of the partial hydrolysis of the symmetrical dioxaborine dyes were first obtained.
