“…The Ru (II) system showed better activity and selectivity than its Os(II) analogue and the selectivity of the systems towards the unsaturated alcohol was enhanced by increasing the substrate to catalyst ratio, salt concentration and ligand tensoactivity. Nuithitikul and Winterbottom [9] reported the biphasic hydrogenation of cinnamaldehyde with RhCl(TFFTS) 3 to the saturated aldehyde with a 99.9% selectivity. The same researchers reported a comprehensive study of the crucial parameters for the biphasic hydrogenation of cinnamaldehyde using Ru/TPPTS systems, achieving a selectivity to the saturated alcohol of 96% and to the unsaturated aldehyde of 97% if the reaction conditions are carefully selected [10].…”

The hydrosoluble complexes [Rh(CO)(Pz)(L)] 2, and [RuH(CO)(CH 3 CN)(L) 3 ][BF 4 ] [L = TPPMS (triphenylphosphinemonosulfonated) and TPPTS (triphenylphosphine-trisulfonated)] were evaluated in the selective hydrogenation of a,b-unsaturated aldhydes in biphasic media The Rh complexes produced the saturated aldehydes while the Ru complexes generated the alcohols with high chemoselectivity. The catalytic phase can be recycled up to five times.

“…Water-soluble ruthenium complexes selectively reduces carbonyl group of a,b-unsaturated aldehydes [20][21][22][23]. Water-soluble rhodium and palladium complexes selectively catalyze the hydrogenation of carbon-carbon double bond to form saturated aldehydes [24][25][26]. It has been shown that water-soluble Ru/TPPTS complex selectively hydrogenate olefinic bond of cinnamaldehyde if certain parameters are controlled [27].…”

Hydrogenation of α,β-Unsaturated Carbonyl Compounds Using Recyclable Water-Soluble FeII/EDTA Complex Catalyst

et al. 2008

Hydrogenation of unsaturated carbonyl compounds like cinnamaldehyde and citral was studied in a biphasic media using water-soluble Fe II /EDTA as a catalyst. It was observed that olefinic bond was selectively hydrogenated over the carbonyl group. Different reaction parameters like temperature, pressure, catalyst concentration were optimized for better selectivity of hydrocinnamaldehyde/ dihydrocitronellal. The catalyst was further extended to hydrogenation of several other a,b-unsaturated carbonyl compounds.

“…Few studies have focused on the liquid-phase selective hydrogenation of cinnamaldehyde to hydrocinnamaldehyde with Pd and Rh noble metal catalysts [6][7][8][9][10][11][12]. Although the Pd and Rh catalysts are active and more selective to the C5C bond hydrogenation, they are costly and scarce.…”

A series of silica supported nickel catalysts were prepared from nickel nitrate and tetraethyl orthosilicate by the sol-gel method with the imidazolium type ionic liquids as solvents. The catalysts were characterized by means of X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). Their catalytic performances for the selective hydrogenation of cinnamaldehyde to hydrocinnamaldehyde were investigated. The results show that the Ni/ SiO 2 catalyst prepared with 1-(2-hydroxyethyl)-3-methylimidazole tetrafluoroborate ionic liquid as solvent exhibits the highest catalytic activity for the reaction. Under the optimal conditions of catalyst dosage (based on the mass of cinnamaldehyde used) 10%, reaction pressure 2 MPa, temperature 373 K and reaction time 2 h, the conversion of cinnamaldehyde and the selectivity to hydrocinnamaldehyde can reach 97.6% and 98.8%, respectively.
