Oxidative Dehydrogenation on Nanocarbon: Revealing the Reaction Mechanism via In Situ Experimental Strategies
Wang, Chao,Liu, Wei,Wei, Shimeng,Su, Dangsheng,Qi, Wei
, p. 397 - 400 (2018/11/23)
Classical mechanistic analysis strategy, including active site chemical titration, kinetic measurement and corresponding isotopic effect and surface reaction of single reactant etc., were performed in oxidative dehydrogenation reactions on nanocarbon. The

Pacman bites selectively! Stable rhodium(III)-N-heterocyclic carbene-hydride complexes (Pacman-like catalysts) are highly active and selective catalysts for H/D exchange at the β position of aromatic α-olefins (see picture). The interplay between bulky N-

(Figure Presented) Kicking the coke habit: In nanocarbon-catalyzed oxidative dehydrogenation of ethylbenzene, oxygen is dissociatively adsorbed, and breaking of C-H bonds in ethylbenzene is kinetically relevant. In contrast to metal-based catalysts, the subsurface structure plays no role in the activity of the nanocarbon catalyst. Unlike activated carbon, the nanocarbon catalysts show no loss of activity from coking or combustion.
Screening catalysts for the catalytic exchange of hydrogen by tritium using magnetic labeling
Niessen, Heiko G.,Ulrich, Claudia,Bargon, Joachim

Isotope labeling is an important method to evaluate drugs and compounds for agricultural use. Therefore, a fast and convenient method to selectively exchange hydrogen against non-radioactive deuterium or radioactive tritium in the final product is desirable. PHIP-NMR investigations of the influence of CO on the selective exchange of the geminal protons in styrene show that CO increases the efficiency of the selective exchange non-linearly and suppresses the hydrogenation of styrene to ethylbenzene.
PREPARATION OF DEUTERIATED 1-PHENYLETHANOLS BY REDUCTIVE DEHALOGENATION OF THE CORRESPONDING HALOGENOACETOPHENONES WITH RANEY ALLOYS IN AN ALKALINE DEUTERIUM OXIDE SOLUTION

Deuteriated 1-phenylethanols were prepared by reductive dehalogenation of the corresponding halogenoacetophenones with Raney Ni-Al and Cu-Al alloys in 5percent NaOD-D2O solution.It was found that the Ni-Al alloy introduced greater than expected numbers of deuterium atoms in the phenyl ring, but the expected deuteriated 1-phenylethanols were obtained in high yield and in high isotopic purity when Raney Cu-Al alloy was used.
