Switchable imine and amine synthesis catalyzed by a tripodal ligand-supported well-defined cobaltcomplex is presented herein. A large variety of primary alcohols and amines were selectively converted to imines or amines in good to excellent yields. It is discovered that the base plays a crucial role on the selectivity. A catalytic amount of base leads to the imine formation, while an excess loading
A clean sweep: Aryl and aliphatic imines can be synthesized directly and efficiently from alcohols and amines under mild, neutral conditions with the liberation of only molecular hydrogen and water (see scheme; R=isopropyl, tert‐butyl). This general, environmentally benign reaction is catalyzed by a de‐aromatized ruthenium PNP pincer complex (0.2 mol %), and can proceed in toluene under an inert atmosphere
一目了然:在温和的中性条件下,醇和胺可仅由分子氢和水释放(见方案; R =异丙基,叔丁基),可直接有效地由醇和胺合成芳基和脂族亚胺。这种一般的,对环境无害的反应是由脱芳香化的钌PNP钳形配合物(0.2摩尔%)催化的,可以在甲苯中于惰性气氛或空气中进行。
Catalytic coupling of nitriles with amines to selectively form imines under mild hydrogen pressure
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。
