Homogeneous catalytic hydrogenation of unsaturated organic compounds

Solid‐Supported Green Synthesis of Substituted Hydrocinnamic Esters by Focused Microwave Irradiation

“…Further, use of microwave irradiation on solid-supported reactions has enhanced the impact of the latter as the high heating efficiency of microwave results in remarkable rate enhancement, higher yields, greater selectivity, and ease of manipulation of such reactions [3]. In addition, the limitation of the microwave-assisted reactions in solvents enforcing development of high pressure and special sealed vessels are circumvented by this solid-support strategy [4], which enables organic reactions such as oxidation, hydrogenation, etc., to occur rapidly at atmospheric pressure and to upscale the reaction on a preparative scale.A lot of hydrogenation protocols are available for the selective hydrogenation of C=C bonds of unsaturated esters which either require a special apparatus and H 2 gas (potentially explosive) [5] …”

Palladium Nanoscale Catalysts in Ionic Liquids: Coupling and Hydrogenation Reactions

“…(Young et al, 1947;Brown & Brown, 1962;Harmon et al, 1969;Ohkuma et al, 1995;Lu et al, 2008) In this context, the preparation and stabilisation of metal NPs becomes a suitable alternative for the classical homogeneous and heterogeneous systems. (Crooks et al, 2001;Thomas et al, 2003;Astruc et al, 2005;Yan et al, 2010) Particularly, metal NPs prepared in ILs proved to be an outstanding recyclable catalytic-phase for the hydrogenation of different substrates exhibiting high catalytic activities.…”
