“…406,407 The metal-hydrogen bond energies have been extensively measured and compared using different techniques. As Pearson has discussed, transition metal hydrides typically do not possess a large dipole, so three different types of behavior may be observed upon M-H bond cleavage (Figure 165).…”

Cofactor-mimetic aerobic oxidation has conceptually merged with catalysis of syngas reactions to form a wide range of Markovnikov-selective olefin radical hydrofunctionalizations. We cover the development of the field and review contributions to reaction invention, mechanism and application to complex molecule synthesis. We also provide a mechanistic framework for understanding this compendium of radical reactions.

“…Industrial processing of the longer chain fatty acids, such as lauric, palmitic, and oleic acid, traditionally focuses on decreasing the degree of unsaturation while maintaining the carboxylic acid group and avoiding isomerization. 1 − 3 Industrial practice favors nickel catalysts operating between 140 and 190 °C and 2–3 bar. 1 , 3 There is also interest in unsaturated alcohols as they are high-value products in pharmaceuticals, cosmetics, and household applications.…”

Radio frequency (RF) induction heating was compared to conventional thermal heating for the hydrogenation of oleic acid to stearic acid. The RF reaction demonstrated decreased coke accumulation and increased product selectivity at comparable temperatures over mesoporous Fe 3 O 4 catalysts composed of 28–32 nm diameter nanoparticles. The Fe 3 O 4 supports were decorated with Pd and Pt active sites and served as the local heat generators when subjected to an alternating magnetic field. For hydrogenation over Pd/Fe 3 O 4 , both heating methods gave similar liquid product selectivities, but thermogravimetric analysis–differential scanning calorimetry measurements showed no coke accumulation for the RF-heated catalyst versus 6.5 wt % for the conventionally heated catalyst. A different trend emerged when hydrogenation over Pt/Fe 3 O 4 was performed. Compared to conventional heating, the RF increased the selectivity to stearic acid by an additional 15%. Based on these results, RF heating acting upon a magnetically susceptible nanoparticle catalyst would also be expected to positively impact systems with high coking rates, for example, nonoxidative dehydrogenations.
