Recent development and modification of the general synthesis of pyrroles and 1-vinylpyrroles by the reaction of ketoximes with acetylenes and their synthetic equivalents (vinyl halides and dihaloalkanes) in the presence of the strongly basic KOH/DMSO catalytic and eliminating pair (the Trofimov reaction) are briefly reviewed. The formation of 3H-pyrroles and other isolable intermediates (O-vinyl ketoximes and hydroxypyrrolines) as well as side products are discussed
