An efficient and organic ligand‐free heterogeneous catalytic system for hydroformylation of olefins is highly desirable for both academy and industry. In this study, simple Rh black was employed as a heterogeneous catalyst for hydroformylation of olefins in the absence of organic ligand. The Rh black catalyst showed good catalytic activity for a broad substrate scope including the aliphatic and aromatic olefins, affording the desired aldehydes in good yields. Taking the hydroformylation of ethylene as an example, 86% yield of propanal and TOF of 200 h–1 were obtained, which was superior to the reported homogeneous catalytic systems. In addition, the catalyst could be reused five times without loss of activity under identical reaction conditions, and the Rh leaching was negligible after each cycle.

Rh颗粒作为催化剂的无有机配体加氢甲酰化†

对于学术界和工业界来说,高效且无有机配体的烯烃加氢甲酰化催化体系是非常理想的。在这项研究中,在没有有机配体的情况下,简单的Rh黑色被用作烯烃加氢甲酰化反应的非均相催化剂。Rh黑色催化剂对包括脂肪族和芳香族烯烃在内的广泛底物范围均显示出良好的催化活性,从而以良好的收率提供了所需的醛。以乙烯的加氢甲酰化为例,丙醛的收率为86%,TOF为200 h –1,优于已报道的均相催化体系。另外,在相同的反应条件下,催化剂可以重复使用五次而不会失去活性,并且在每个循环后Rh的浸出量可以忽略不计。
