Advanced Synthesis &Catalysis, EarlyView.Herein, the first asymmetric [4+2] cycloaddition is reported, utilizing in situ‐generated dienes from isochromane‐3,4‐diones and nitroalkenes, catalyzed by a bifunctional thiourea organocatalyst and Brønsted base cocatalysts, yielding highly enantioselective bridged and spiro lactones, with further investigations into novel reactivity and product ...

Advanced Synthesis &Catalysis, EarlyView.A Ti(III) complex synthesized mechanochemically catalyzes the cycloaddition of CO2 (1 bar) with terminal, internal, and trisubstituted epoxides. Mechanistic studies by density functional theory calculations reveal that the superior activity of Ti(III) compared to Ti(IV) arises from its lower oxophilicity, facilitating CO2 insertion into Ti–O bonds, as ...

Low Temperature Oxidation of Cyclohexane: Uncertainty of Important Thermo-Chemical Properties
Eurasian Chemico-Technological Journal, 2018 The study of the standard formation enthalpy, entropy, and heat capacity for key species relevant to the low-temperature combustion of cyclohexane has been performed by applying the group additivity method of Benson. The properties of 18 Benson groups (8

Advanced Synthesis &Catalysis, EarlyView.Electron‐deficient alkenes can be functionalized with α‐amino, α‐alkoxy and α‐alkylthio radicals formed by Fe‐photocatalyzed decarboxylation of the corresponding carboxylic acids. The reactions proceed under smooth ligandless conditions with inexpensive base and in the absence of oxidant. A mechanistic computational TD‐DFT study supports the occurrence
