Herein, we describe an efficient coupling of alcohols and amines catalyzed by well-defined isoelectronic hydride MnIand FeIIcomplexes, which are stabilized by a PNP ligand based on the 2,6-diaminopyridine scaffold. This reaction is an environmentally benign process implementing inexpensive, earth-abundant non-precious metal catalysts, and is based on the acceptorless alcohol dehydrogenation concept. A range of alcohols and amines including both aromatic and aliphatic substrates were efficiently converted in good to excellent isolated yields. Although in the case of Mn selectively imines were obtained, with Fe—exclusively monoalkylated amines were formed. These reactions proceed under base-free conditions and required the addition of molecular sieves.

The synthesis of two novel bis-aminophosphonates bearing anthracene rings-bis[N-methyl(diethoxyphosphonyl)-1-(9-anthryl)]benzidine (3) and 4,4-bis[N-methyl(diethoxy-phosphonyl)-1-(9-anthryl)]diaminodiphenylmethane (4)-via the Kabachnik-Fields reaction is reported. The compounds have been characterized by elemental analysis, TLC, IR, NMR (1H, 13C, 31P) and fluorescent spectra. The reaction leads to a mixture of the two possible forms (meso and racemic), with predominant formation of one of the diastereomers. The recrystallized compounds 3 and 4 consist of only one diastereomer. A racemization at the chiral centers and a cleavage of the C-P bond are observed in the alkaline hydrolysis of the new compound 4 and three previously described aminophosphonate derivatives 5-7.
