of direct conversion of tertiary alcohols bearing a β-hydrogen atom to vicinal halohydrins—chlorohydrins and bromohydrins—under green reaction conditions was tested preliminarily on model tertiary benzyl alcohols. Tertiary alcohols were successfully directly halogenated to vicinal halohydrins with N-halosuccinimide in aqueous media. The efficiency of the reaction in water was significantly improved

types of brominecomplexes with various polymers bearing basic units (pyridine, piperidine and piperazine) were investigated and the role of polymer matrices on reactivity was tested by three types of organicreactions: electrophilic addition, aromatic substitution and radical substitution. Pyridine complex (1a) was most reactive in all three types of reactions, while immobilisation of bromine to polymers

electrochemical technology to enable alkene alkoxyhalogenation and organohalide dehalogenation in one pot is presented. This technology is highlighted by convergent strategy integrating several reactions, such as alkene alkoxyhalogenation, organohalide dehalogenation, and dehalogenation deuteration. Experimental data suggest that alkenes have the lowest oxidation potential, which lead to anodic conversion
