The synthetic protocol for the reduction of alcohols to hydrocarbons by using hydriodic acid, first described by Kiliani more than 140 years ago, was improved to be more applicable to organic synthesis. Instead of a strongly acidic, aqueous solution,

Density functional theory and extrapolated CCSD(T) computations of several "anti-Bredt" alkenes were carried to explore possible 1,2-diyl "alkene" candidates with a triplet ground state. Ten candidates containing twisted double bonds at the bridgehea

In this essay some important forerunners of green chemistry will be discussed and compared with the present state. The relationship to ethics will be considered. Starting from the new movement of green chemistry by Anastas, some important highlights

Steric strain, caused by forced deformation of double bond geometry, has significant impact on alkene reactivity, as was shown by a study of the gas-phase basicity of (E)-1-methyl-2-(1-methyl-2-adamantylidene)adamantane. The Gibbs free energy of the

Environmental factors and process mass intensity were determined and evaluated for more than 30 standard procedures for the synthesis of alkenes with tri- and tetrasubstituted double bonds. They contain some of the most commonly used reaction types f

3-Chlorocarbazole, 3,6-dichlorocarbazole, dibromocarbazole, and 1,3,6,8-tetrabromocarbazole are emerging environmental contaminants which have been detected recently in water, sediment, and soil samples. However, their sources and occurrence have not

Six cyclic stilbene derivatives with hindered free rotation around the C(vinyl)–C(phenyl) single bond were synthesized by McMurry coupling. The torsion angles around the double and the single bond, and the CC bond length were obtained for many of t
