Auto‐Tandem Catalysis: PdII‐Catalysed Dehydrogenation/Oxidative Heck Reaction of Cyclopentane‐1,3‐diones
A PdII catalyst system has been used to successfully catalyse two mechanistically distinct reactions in a one-pot procedure: dehydrogenation of 2,2-disubstituted cyclopentane-1,3-diones and the subsequent oxidative Heck coupling. This auto-tandem catalytic reaction is applicable to both batch and continuous flow processes, with the latter being the first example of a tandem aerobic dehydrogenat...
متن کاملOxidative Dehydrogenation of Methanol to Formaldehyde’
is not favorable (AH = + 3 1.5 kcal). Our conclusion is that an important catalytic site involves two adjacent surface dioxo units (the dual dioxo site), with each dioxo site extracting one H in a sequence of steps. The required dual dioxo site exists on the (010) surface of MOO, but does not exist on the other low index surfaces. This mechanism is supported by atmospheric pressure experimental...
متن کاملA highly efficient oxidative condensation reaction for selective protein conjugation.
We hereby report a mild and efficient coupling reaction between alkyl aldehydes and aryl diamines. In the presence of a Cu(2+) or a Zn(2+) ion, oxygen (O2) in air is able to promote the oxidative condensation of the two readily preparable functional groups, forming stable benzimidazole linkages in neutral aqueous solution at room temperature (RT). We demonstrated that the reaction could be util...
متن کاملCatalysis over Nanocarbon: Styrene Synthesis and Nh3 Decomposition
Nanocarbons (graphite, tube, diamond) were used as highly efficient catalyst for styrene synthesis from oxidative dehydrogenation of ethylbenzene. Long-time stability and outstanding performance suggested a much more promising future for industrialization of nanocarbon. Metal-free nanocarbons are not highly active for NH3 decomposition while residual metal nanoparticles in commercial CNTs could...
متن کاملRole of ceria in oxidative dehydrogenation on supported vanadia catalysts.
The effect of the suppport on oxidative dehydrogenation activity for vanadia/ceria systems is examined for the oxidation of methanol to formaldehyde by use of well-defined VO(x)/CeO(2)(111) model catalysts. Temperature-programmed desorption at low vanadia loadings revealed reactivity at much lower temperature (370 K) as compared to pure ceria and vanadia on inert supports such as silica. Densit...
