Impregnated Copper(II) Oxide on Magnetite as Catalyst for the Synthesis of Benzo[b]furans from 2-Hydroxyarylcarbonyl Derivatives and Alkynes

The coupling-allenylation-cyclization reaction sequence of o-hydroxybenzaldehydes with alkynes in the presence of 4-methylbenzenesulfonohydrazide was carried out in ethanol as a nontoxic biorenewable solvent and in the presence of impregnated copper(II) oxide on magnetite as a heterogeneous catalyst...
