Kinetic Properties of Caged Ambident Radicals Formed in the Thermolyses of Nitrones

Thermal decompositions of N-benzhydryl-α,α-diphenylnitrone (1) and the para-tetradeuterated analogue 1-d4 in several solvents are reported.Mass spectral analyses of recovered nitrones and/or O-benzhydryl ethers were performed.These data are combined with previously reported spectroscopic rate constants for the decomposition of 1 to evaluate the true carbon-nitrogen homolysis rate constant and the relative rate constants for (a) geminate radical recombination at the iminoxy nitrogen, (b) irreversible recombination at oxygen, and (c) diffusion of the solvent-caged radicals.

Metallic Barium: A Versatile and Efficient Hydrogenation Catalyst

Ba metal was activated by evaporation and cocondensation with heptane. This black powder is a highly active hydrogenation catalyst for the reduction of a variety of unactivated (non-conjugated) mono-, di- and tri-substituted alkenes, tetraphenylethylene, benzene, a number of polycyclic aromatic hydrocarbons, aldimines, ketimines and various pyridines. The performance of metallic Ba in hydrogenation catalysis tops that of the hitherto most active molecular group 2 metal catalysts. Depending on the substrate, two different catalytic cycles are proposed. A: a classical metal hydride cycle and B: the Ba metal cycle. The latter is proposed for substrates that are easily reduced by Ba0, that is, conjugated alkenes, alkynes, annulated rings, imines and pyridines. In addition, a mechanism in which Ba0 and BaH2 are both essential is discussed. DFT calculations on benzene hydrogenation with a simple model system (Ba/BaH2) confirm that the presence of metallic Ba has an accelerating effect.

Synthesis of Dibenzyls by Nickel-Catalyzed Homocoupling of Benzyl Alcohols

Dibenzyls are essential building blocks that are widely used in organic synthesis, and they are typically prepared by the homocoupling of halides, organometallics, and ethers. Herein, we report an approach to this class of compounds using alcohols, which are more stable and readily available. The reaction proceeds via nickel-catalyzed and dimethyl oxalate assisted dynamic kinetic homocoupling of benzyl alcohols. Both primary and secondary alcohols are tolerated.
