Hydrogenation of an alkene is when the alkene is turned into an alkane. Hydrogen gas is added to the alkene double bond, breaking the pi bond and keeping the sigma bond. What reagent reduces alkenes? Hydrogen gas, H2, reduces the alkenes. This reaction also requires the use of a metal ca...
As a case study, we show here that oil-in-water Pickering emulsions stabilized by Pd nanoparticles immobilized on molecularly modified carbon nanotubes (Pd/CNTs) is an efficient electrocatalytic system for alkene ECH (Fig. 1b). Our system outperforms the reported Pd membrane reactor23 and ...
PROBLEM TO BE SOLVED: To obtain a Pd type catalyst effective for hydrogenation of an alkyne into an alkene by specifying contents and atomic ratios of respective components in a catalyst comprising palladium, an alkali metal, fluorine and an inorg. support material.SUKOTSUTO EICHI BURAUN...
A hydrogenation reaction is a specific type of addition reaction where molecular hydrogen is added onto a different molecule across a double bond. While this can happen across any double bond, like a ketone, the addition of hydrogen most often occurs on an alkene, or a carbon-carbon double bo...

Homogeneous Hydrogenation of Alkenes, Alkynes, Allenes, and 1,3-Dienes Except perhaps with [HCo(CN) 5 ] 3 , it is clear that for hydrogenation an alkene or alkyne must first be co-ordinated to the metal centre of the catalytic complex. It is a familiar observation [1] in heterogeneous ...
Here we report an asymmetric hydrogenation of allylic alcohols using an Ir–N,P-ligand complex via DKR. In contrast to the many DKRs involving carbonyl reduction, this methodology allows for DKR during alkene reduction. Mechanistic studies support the hypothesis that racemization of the substrate ...

(1) The overgrowth of an atomic overlayer of 2D microporous Cu2O on Pd is the key to enhancing the selectivity toward semi-hydrogenation due to the formation of 2D Cu2O/Pd catalytic interface. (2) The alloy of Cu(0) with Pd is the main contributor to the enhanced activity due to the ...
