摘要

This paper reports the synthesis, structure, and properties of a series of PNP pincer complexes of osmium OsH_3Cl[HN(C_2H _4PiPr_2)_2] (1), OsH _3[N(C_2H_4PiPr_2) _2] (2), OsH_4[HN(C_2H_4P iPr_2)_2] (3), and OsH_2(PMe _3)[HN(C_2H_4PiPr_2) _2] (4). The tetrahydride 3 operates as an efficient catalyst at 0.1 mol% loading for the reactions of amination and dehydrogenative coupling of primary alcohols, producing secondary amines and symmetrical esters, respectively. The catalyst 3 is distinguished by outstanding stability, and it can be used in an aqueous environment at temperatures as high as 200 °C.
