The direct reductive N-arylation of nitromethane by organophosphorus-catalyzed reductive C-N coupling with arylboronic acid derivatives is reported. This method operates by the action of a small ring organophosphorus-based catalyst (1,2,2,3,4,4-hexamethylphosphetane P-oxide) together with a mild terminal reductant hydrosilane to drive the selective installation of the methylamino group to (hetero)aromatic boronic acids and esters. This method also provides for a unified synthetic approach to isotopically labeled N-methylanilines from various stable isotopologues of nitromethane (i.e., CD3NO2, CH315NO2, and 13CH3NO2), revealing this easy-to-handle compound as a versatile precursor for the direct installation of the methylamino group.

The present paper describes different preparations of iron-porphyrin-nitrosoalka complexes and their study by various spectroscopic methods including an X-ray analysis. This study definitely proves the existence of the Fe**I**I-RNO bond, establishes the end-on N-binding mode of nitrosoalkanes in these ferroporphyrin complexes and gives information on the electronic structure of the Fe-RNO bond. Moreover, it points out a striking similarity between the bonding properties of nitrosoalkanes and dioxygen as ligands of iron(II)-porphyrins. Refs.
