Investigation of cyclohexene thermal decomposition and cyclohexene + OH reactions

open access: yesCombustion and Flame, 2023
Cyclohexene is a common intermediate in the oxidation of cyclohexane and alkyl-substituted cyclohexanes. It also plays an important role in the formation of polycyclic aromatic hydrocarbons (PAHs) by providing a route for the first aromatic ring. Two types of reactions are highly important in cyclohexene kinetics, i.e., H-abstraction by OH radicals and

One-pot and metal-free synthesis of 3-arylated-4-nitrophenols via polyfunctionalized cyclohexanones from β-nitrostyrenes

open access: yesBeilstein Journal of Organic Chemistry, 2020
β-Nitrostyrenes underwent a Diels–Alder reaction with Danishefsky’s diene to afford cyclohexenes together with the corresponding hydrolyzed products, 3-arylated-5-methoxy-4-nitrocyclohexanones.

Stereospecific Ring Contraction of Bromocycloheptenes through Dyotropic Rearrangements via Nonclassical Carbocation-Anion Pairs [PDF]

open access: yes, 2018
Experimental and theoretical evidence is reported for a rare type I dyotropic rearrangement involving a [1,2]-alkene shift, leading to the regio- and stereospecific ring contraction of bromocycloheptenes.

Oxidation of acyclic alkenes and allyl and benzyl ethers with DIB/t-BuOOH/Mg(OAc)2 [PDF]

open access: yes, 2012
Oxidation of (11Z)-1′,2′-didehydrostemofoline with DIB/TBHP/Mg(OAc)2·4H2O resulted in oxidative cleavage of the C-11-C-12 double bond instead of the desired allylic oxidation of the 1-butenyl side chain. Stemofoline gave a similar result.

Highly-functionalised difluorinated cyclohexane polyols via the Diels–Alder reaction : regiochemical control via the phenylsulfonyl group [PDF]

open access: yes, 2005
A difluorinated dienophile underwent cycloaddition reactions with a range of furans to afford cycloadducts whichcould be processed regio- and stereoselectively via episulfonium ions, generated by the reaction between their alkenyl groups and ...

Synthesis and Reactivity of a Mono‐Coordinated Triplet Bismuthinidene

open access: yesAngewandte Chemie, EarlyView.
Dehydrogenation of Ar*BiH2 3 yielded the kinetically stabilized mono‐coordinated triplet bismuthinidene 4, which was structurally characterized by sc‐XRD and whose electronic character was analyzed by quantum chemical calculations. Bismuthinidene 4 reacts with alkyl halides with oxidative addition to bismuthanes Ar*Bi(R)X, which react with LiAlH4 to ...

A Bifunctional Organic Photocatalyst for Efficient Single‐Electron and Energy Transfer Activation

open access: yesAngewandte Chemie, EarlyView.
Thioaryl hydroxycoumarins are versatile, metal‐free photocatalysts for both single‐electron (SET), and energy transfer (EnT) pathways, enabling radical and triplet energy transfer reactions with a single organic scaffold. Abstract Bifunctional photocatalysts capable of mediating both single‐electron transfer (SET) and energy transfer (EnT) processes ...
