“…Thus imidazoles and benzimidazoles containing chalcogenophosphoryl and hydroxyl functions are efficient ligands for directing the synthesis of promising biologically active metal complexes [11][12][13][14] and also as models for studying several physicochemical aspects [12][13][14]. One of the convenient routes for the synthesis of functional heterocyclic groups can be the reaction of the secondary pyridylphosphine chalcogenides 1, 2 with 2-formyl-1-organylimidazoles 3, 4 and -benzimidazoles 5, 6.…”
