Abstract

N\'-[(4-oxochromen-3-yl)methylidene]-4-R-furo[3,2-b]pyrrole-5-carboxhydrazides 3 were prepared by treatment of substituted carboxhydrazides 1 with 4-oxo-4H-chromen-3-carboxaldehyde 2 in ethanol in the presence of p-TsOH. Compounds 3 were subsequently used as ligands in complexation reactions with solutions of metal (M²⁺) chlorides or nitrates: [Ni(NO₃)₂.6H₂O, Co(NO₃)₂.6H₂O, CoCl₂.6H₂O, CuCl₂.2H₂O] to give complexes 4.
