N-Bromosuccinimide or NBS is a chemical reagent used in radical substitution, electrophilic addition, and electrophilic substitution reactions in organic chemistry. NBS can be a convenient source of Br • , the bromine radical.
The Wohl–Ziegler reaction [1] [2] is a chemical reaction that involves the allylic or benzylic bromination of hydrocarbons using an N-bromosuccinimide and a radical initiator. [3] Best yields are achieved with N-bromosuccinimide in carbon tetrachloride solvent. Several reviews have been published. [4] [5]
chemical reactions for the Kharasch addition reaction of chloroform to a terminal alkene. The Kharasch addition is an organic reaction and a metal-catalysed free radical addition of CXCl 3 compounds (X = Cl, Br, H) to alkenes. [1] The reaction is used to append trichloromethyl or dichloromethyl groups to terminal alkenes.
The Bouveault aldehyde synthesis (also known as the Bouveault reaction) is a one-pot substitution reaction that replaces an alkyl or aryl halide with a formyl group using a N,N-disubstituted formamide. [1] [2] For primary alkyl halides this produces the homologous aldehyde one carbon longer. For aryl halides this produces the corresponding ...
The von Braun reaction is an organic reaction in which a tertiary amine reacts with cyanogen bromide to an organocyanamide. [1] An example is the reaction of N,N-dimethyl-1-naphthylamine: [2] These days, most chemist have replaced cyanogen bromide reagent with chloroethyl chloroformate reagent instead. It appears as though Olofson et al. was ...

For example, one can take advantage of the propensity of HOCl to undergo this addition reaction by adding a sacrificial alkene-containing chemical to the reaction mixture. This alternate substrate reacts with the HOCl, preventing the HOCl from undergoing reactions that interfere with the Pinnick reaction itself.
