Tandem dehydrogenation-olefin-metathesis catalyst systems, comprising a pincer-ligated iridium-based alkane dehydrogenation catalyst and a molybdenum-based olefin-metathesis catalyst, are reported to effect the metathesis-cyclooligomerization of cyclooctane and cyclodecane to give cycloalkanes with various carbon numbers, predominantly multiples of the substrate carbon number, and polymers.

A Fe(acac)3-catalyzed decarboxylative coupling of 2-(aryl)vinyl carboxylic acids with cycloalkanes was developed by using DTBP as an oxidant through a radical process. This reaction tolerates a wide range of substrates, and products are obtained in good to excellent yields (71-95%). The reaction also shows excellent stereoselectivity, and only trans-isomers are obtained.

By the incorporation of N atoms into naphthalene, we present a theoretical investigation to seek for improved organic hydrogen carriers with an explicit guideline, the release of H2 is found to be greatly favored thermodynamically and the corresponding cycloalkanes possess high hydrogen storage capacity, this offers extensive candidates for practical applications of the promising hydrogen energy.

This paper presents the approach and the results of a kinetic generator in the area of hydrocarbon pyrolysis mechanisms. Radical formation and successive radical decomposition are taken into account. Care is paid to the description of molecule identification procedure and to its homomorphism which enables unique and no ambiguous reactions. New results referring to the pyrolysis of olefins as we...

This paper presents a review of gas-phase detailed kinetic models developed to simulate the low temperature oxidation and autoignition of gasoline and diesel fuel components (alkanes, ethers, esters, alkenes, cycloalkanes, aromatics, including from 4 atoms of carbon) and of mixtures of several of them, which have been proposed as surrogates. The recently proposed models are summarized, as well ...

Abstract The direct and selective C(sp 3 )-H functionalization of cycloalkanes alkanes is a highly useful process in organic synthesis owing to the low-cost starting materials, high step atom economy. Its application asymmetric catalysis, however, has been scarcely explored. Herein, we disclose our effort toward this goal by incorporation dual photocatalysis chiral nickel catalyst commercially ...

Role of transition metals (Ni, Cu, Fe, and Zn) on MoS2 supported alumina was studied for the HDO propylguaiacol (PG) to produce aromatics, cycloalkanes, phenolics. A kinetic model proposed elucidating reaction pathway PG.
