Thermolysis kinetics of diethyl 2,3-dicyano-2,3-di(p-substituted phenyl)succinates

An experimental approach was developed to determine the intrinsic thermolysis rate constants of the central carbon-carbon bond during the dl/meso isomerization of diethyl 2,3-dicyano-2,3-di(p-substituted phenyl)succinates (G=H, Me, OMe, Cl, and NO2/

Potassium fluoride on alumina: Oxidative coupling of acidic carbon compounds with diiodine

Diiodine reacts at room temperature with activated methylene compounds in the presence of potassium fluoride on alumina and saturated dimers, unsaturated dimers or trimers were formed according to the stoechiometry of the reaction. The reactions were improved by using ultrasound activation.
