Manganese complexes with tridentate PNN ligands have been synthesized as catalysts for hydrogenative cross-coupling reaction of nitriles and amines to form secondary imines. This reaction afforded a variety of unsymmetrical secondary imines in good yields with excellent selectivity. Investigation of catalyst intermediates indicated that an amido manganese complex may be the active catalyst species
Imines are selectively formed by coupling of nitriles and amines under mild hydrogen pressure. The reaction is catalyzed by a bipyridine-based PNN Ru(II) pincer complex and proceeds under mild, neutral conditions at 4 bar of H(2).
亚胺是通过在适度的氢气压力下将腈和胺偶联而选择性形成的。该反应由基于联吡啶的PNN Ru(II)夹杂物催化,并在4 bar H(2)的温和中性条件下进行。
