Pd-catalyzed hydrogenolysis4,5-epoxy-2-alkenoateπ–σ–π interconversionpolyoxypeptinPalladium-catalyzed hydrogenolysis of 4,5-epoxy-2-alkenoates to 5-hydroxy-2-alkenoates was examined, and it was shown that the ( Z )-alkenoate with a bulky substituent at C-4 underwent hydrogenolysis with a...
Three broad reactions are examined: decarbonylation, hydrogenation, and hydrogenolysis. Especially striking are the multiple roles of formic acid in hydrogenolysis/hydrogenation and in suppressing decarbonylation, as illustrated by the conversion of HMF to DMF. Hydrogenation of the furan ring is ...
46,47,48,49,50,51,52. Recently, we developed a palladium-catalyzed asymmetric hydrogenation and hydrogenolysis of α-acyloxy ketones with excellent yields and highS/C(up to 5000–6000) using the bulky ligand DTBM-SegPhos51,52. In continuation...

Then, methoxycyclohexane and cyclohexanol were produced through hydrogenolysis and demethoxylation of 2-methoxycyclohexanone. 1- Methylpropyl cyclohexane can possibly be formed through alkylation of methoxycyclohexane and cyclohexanol. Meanwhile, 2-cyclohexene-1-ol might be produced from oxidation of ...

Bimetallic Cu-Pd, in contrast to monometallic Cu and Pd, favored sequential C–OH hydrogenolysis and C=O hydrogenation of the intermediates, resulting in the production of 2,5-DMF with a high yield of 73.4% during the one-pot conversion of sucrose at 200 °C and 1 MPa H2 for 3 h. ...
