Herein, we describe a visible light-promoted intramolecular difluoramidation reaction of olefins. By precisely adjusting the reaction conditions, the difficult-to-control olefin radical addition process was effectively controlled. Heck-type coupling of olefins and hydrofluoroamidation of olefins, as well as difunctionalization of olefins, were successfully achieved with good selectivity.

A visible-light-mediated chlorotrifluoromethylation catalyzed by a copper-based photo-redox catalyst of internal alkenes is reported. The reaction proceeds with complete regioselectivity under mild reaction conditions using commercially available FCSOCl as both the trifluoromethyl and chlorine source, leading to the synthesis of added-value chemicals with atom-economy. A vast array of internal alkenes were functionalized in decent to good yields, highlighting a great tolerance to various functional groups.

Kadcotriones and kadcoccitanes, renowned for their intricate 6/6/5-tricyclic and 6/6/5/6-tetracyclic ring systems, respectively, exhibit promising biological activities. This work proposes a biosynthetic pathway that elucidates how nature synthesizes these triterpenoids from lanosterol. Inspired by this pathway, we present the first biomimetic syntheses of kadcoccitane H and kadcotrione C methyl ester.

A methodology for radical cross-coupling with vinylsiloxanes and pyridinium salts under nickel catalysis is described. Easily implemented from inexpensive and abundant primary amines and terminal alkynes, this Hiyama coupling provides efficient access to (), (), and ()-alkenes with selectivity control. Operating under mild conditions, this robust strategy applies to a broad range of functional groups with diverse double bond stereochemistries.

The present work investigates the impact of the external electric field (EEF) on the oxidizing power of N 2 O, by employing kinetics and quantum chemical calculations. We have taken the oxidation of olefin (Ethene and cyclohexene) by N 2 O as a prototype to demonstrate the effectiveness of EEF. The investigation suggests that the reaction barrier is significantly reduced by choosing an electric field in an appropriate direction.

We report that the cationic iridium complex (PCP)IrH catalyzes the transfer-dehydrogenation of alkanes to give alkenes and hydrogen isotope exchange (HIE) of alkanes and arenes. Contrary to established selectivity trends found for C-H activation by transition metal complexes, strained cycloalkanes, including cyclopentane, cycloheptane, and cyclooctane, undergo C-H addition much more readily than -alkanes, which in turn are much more reactive than cyclohexane. Aromatic C-H bonds also undergo H/D exchange much less rapidly than those of the strained cycloalkanes, but much more favorably than cyclohexane.
