The cathode process for the manufacture of aluminium in industrial cells is discussed with reference to the nature of the dissolved metal in the system NaF-AlF3-Al2O3-CaF2-Al. A new mechanism for the so-called back reaction is outlined, mainly based on a literature review and some other ...

Reaction of Alkenes With Hydrohalic Acids (HCl, HBr, HI) Markovnikov’s Rule: The Halide Adds To The Most Substituted Carbon Stereoselectivity (or Lack Thereof) In Alkene Hydrohalogenation Hydrohalogenation of Alkenes: The Mechanism The Reaction Energy Diagram Carbocation Rearrangements – Hydride and...
Primary alkyl halides have broad utility as fine chemicals in organic synthesis. The direct halogenation of alkenes is one of the most efficient approaches for the synthesis of these halides. Internal alkenes, in particular mixtures of isomers from refin
The textbook alkene halogenation reaction establishes straightforward access to vicinal dihaloalkanes. However, robust catalytic methods to perform dihalogenation in a stereoselective manner are lacking, despite the ubiquity of contiguous halogen-bearing stereocentres in natural products, bioactive and pharmace...
The reaction with N-bromosaccharin gives para- substituted compounds only, whereas N-chlorosaccharin produces orto and para mixtures (para isomer predominantly, ca. 4-5 : 1). The reactions of the N-halosaccharins with alkenes (cyclohexene, styrene, a-methylstyrene, and 1-hexene) give the ...
A new method for the mixed halogenation of alkenes has been proposed based on the reaction of olefins with N-chloroamines in the presence of phosphorus bromide or oxybromide. The plausible reaction mechanism and the results of reactions with a number of model unsaturated compounds such as ...
