Dehydrogenation of Phenols. I. Dehydrogenation of 2,6-Dimethylphenol with Silver Oxide.

Palladium-catalyzed aerobic dehydrogenation of substituted cyclohexanones to phenols.

Aromatic molecules are key constituents of many pharmaceuticals, electronic materials, and commodity plastics. The utility of these molecules directly reflects the identity and pattern of substituents on the aromatic ring. Here, we report a palladium(II) catalyst system, incorporating an unconventional ortho-dimethylaminopyridine ligand, for the conversion of substituted cyclohexanones to the c...

Catalytic dehydrogenation of isopentane with iridium catalysts.

The catalytic activation of alkanes under mild conditions to give the corresponding alkenes and hydrogen has tremendous industrial implications because olefins are the most important starting materials for large-scale industrial processes such as olefin polymerization, dimerization, oligomerization, hydroformylation, and metathesis. In the search for a process by which olefins can be produced f...

Modeling lignin polymerization. I. Simulation model of dehydrogenation polymers.

Lignin is a heteropolymer that is thought to form in the cell wall by combinatorial radical coupling of monolignols. Here, we present a simulation model of in vitro lignin polymerization, based on the combinatorial coupling theory, which allows us to predict the reaction conditions controlling the primary structure of lignin polymers. Our model predicts two controlling factors for the beta-O-4 ...

Dehydrogenation of Benzene on Liquid

The reactions of benzene on Al100 + have been investigated as a function of cluster temperature (300−1100 K) and relative kinetic energy (1−14 eV) by low-energy ion-beam methods and mass spectrometry. Benzene chemisorbs on both solid and liquid aluminum clusters to generate Al100C6D6 . A series of Al100−n + (n = 1, 2, 3, ...) products was also observed. As the cluster temperature was raised abo...
