The ring-opening of 2-methylfuran and 2,3-dihydro-5-methylfuran catalyzed by the Lewis acid catalyst tris­(pentafluorophenyl)­borane in the presence of hydrosilanes was studied using quantum chemical methods. In a previous study, it was suggested that the stereoselective formation of the product is due to a nucleophilic vinylic substitution (SNV) during the reaction. Our calculations show that the pathway involving the SNV reaction is energetically not accessible. Instead, the intramolecular C–O...

Some nitroxides, eg. tetramethylpyridiniumoxide (TEMPO), are known as stable radicals; however, carbazole nitroxide is less stable. The kinetic stabilization of labile radicals by introduction of bulky substituents is usually effective to investigate intrinsic properties of the molecule because of small electronic perturbation induced by the substituents. In this study, macrocage molecules with a carbazole nitroxide connected by covalent bonds were newly designed as kinetically stabilized carbaz...

Recent studies have demonstrated the capabilities of amidyl radicals to facilitate a range of intermolecular functionalizations of unactivated, aliphatic C–H bonds. Relatively little information is known regarding the important structural and electronic features of amidyl and related radicals that impart efficient reactivity. Herein, we evaluate a diverse range of nitrogen-centered radicals in unactivated, aliphatic C–H chlorinations. These studies establish the salient features of nitrogen-cent...

Cross-coupling reaction between two C–H bonds has become a fundamental strategy in synthetic organic chemistry. With the increasing importance in green chemistry, atom economy, and step economy, its development has sky-rocketed within the last twenty years, with the term “cross-dehydrogenative coupling (CDC)” popularized and progressed by the group of Li and oth-ers to describe direct Y–Z bond formations from Y–H and Z–H bonds under oxidative conditions. Among all types of CDC reactions, the C–C...

Enamines are electron-rich compounds bearing intriguing redox properties. Herein, a series of secondary enamines condensed from primary amine and β-ketocarbonyls were synthesized and their electrochemical oxidation properties were systematically studied by cyclic voltammetry. Furthermore, theoretical calculation of oxidation potentials of enamines, particularly those catalytic intermediates, was also conducted to further broaden the scope investigated. Possible structural factors on oxidation as...
