The method of investigation - The condition of exact solvability of two-dimensional dilaton semiclassical theories of gravitation are formulated in the general form as one condition on the coefficients of the gravitation-dilaton Lagrangian. The corresponding class of models includes all previously known models of such a kind. Within this class we encounter different types of solutions including black holes and cosmological metrics. We study properties of solutions with essential backreaction. It is shown that in the framework of semiclassical dilaton gravity extremal black holes do exist both among exactly solvable models and in a general case.
