N-Aryl- or N-heteroarylformamides are prepared by hydrogenating a corresponding nitroarene or nitroheteroarene with formic acid and/or ammonium formate as hydrogen donor and formylating agent in the presence of at least one noble metal-based hydrogenation catalyst and a vanadium or molybdenum compound as co-catalyst.

A thermoplastic polyurethane is formed by the reaction of a specific hydroxy-diterminated poly(phenylene ether) and an organic diisocyanate. The polyurethane-forming reaction optionally employs diols other than the hydroxy-diterminated poly(phenylene ether). Compared to thermoplastic polyurethanes lacking the residue of the hydroxy-diterminated poly(phenylene ether), the thermoplastic polyurethanes described herein exhibit properties including one or more of improved heat and oxidation resistance, improved resistance to acids, bases, and solvent, and reduced water absorption.
