Ignition delay times of small alkenes are a valuable constraint for the refinement core kinetic mechanism hydrocarbons used in representing combustion properties real fuels. Moreover, chemical reactivity comparison those provides reference object-oriented fuel design and logical utilization. In this study, ignition C2–C4 (ethylene, propene 1-butene) were measured behind reflected shock waves fi...

Alkenes are the most ubiquitous pro-chiral functional groups accessible to synthetic chemists. For this reason, difunctionalization reactions of alkenes are particularly important, as they can be used to access highly complex molecular architectures.1,2 Stereoselective oxidation reactions, including dihydroxylation, aminohydroxylation and halogenation reactions,3,4,5,6 are well-established meth...

While the activation of relatively inert gases such as N2 and CO with organometallic complexes remains a topic of intense investigation, methods for controlling the reactivity of nitric oxide at transition-metal centers have received considerably less attention. For example, the migratory insertion of NO into metal–alkyl or metal–aryl bonds has been observed in only a handful of metal complexes...

We report here kinetic and isotopic evidence for the elementary steps involved in dimethyl ether (DME) homologation and for their role in the preferential synthesis of 2,2,3-trimethylbutane (triptane) and isobutane. Rates of methylation of alkenes and of hydrogen transfer, isomerization and b-scission reactions of the corresponding alkoxides formed along the homologation path to triptane were m...

Intermolecular photocatalytic hydroaminoalkylation (HAA) of alkenes have emerged as a powerful method for the construction alkyl amines. Although there are some studies aiming at stereoselective HAA reactions, limited to electrophilic alkenes. Herein, we report highly regio-, diastereo-, and enantioselective electron-rich dienol ethers ?-amino radicals derived from acids using unified photoredo...

The systematic combination of N-heterocyclic olefins (NHOs) with fluoroarenes resulted in twisted push-pull alkenes. These alkenes carry electron-donating cyclicdiamino substituents and two electron-withdrawing fluoroaryl the geminal positions. synthetic method can be extended to a variety substituted by varying NHO as well fluoroarenes. Solid-state molecular structures these molecules reveal n...

manganese metal-organic framework (mn-mof) containing mn2+ ions, benzenetricarboxylic acid (btc) and n,n-dimethylformamid (dmf) was prepared and used as catalyst for oxidation of alkenes such as 1,1-diphenylethylene, trans-stilbene, cyclohexene, norbornene, styrene and cyclooctene to epoxides with 33-92% conversion and 75-100% selectivity and oxidation of alkanes such as fluorene, adamantane, e...

In this minireview, we explore the different approaches used to perform hydrofluorination reaction of alkenes. Contrary other hydrohalogenation reactions, requires specific conditions due lower reactivity HF. Over years, many have been explored among which use HF complexes has particularly proved be useful as these reagents are easier handle. The enantioselective demonstrated using electrophili...
