Abstract
alpha-Halo-beta-oxoaldehydes react with o- and m-phenylenediamines to give alpha-halo-beta-oxoenamines. In the case of o-phenylenediamine, t he initially formed monoenamine undergoes concurrent intramolecular cy clization to give benzimidazole and a halocarbonyl compound. alpha,alp ha-Dihalo-beta-oxoaldehydes react with o- and m-phenylenediamines acco rding to the haloformic decomposition scheme involving formylation of amino groups.
