NBS is commercially available. It can also be synthesized in the laboratory. To do so, sodium hydroxide and bromine are added to an ice-water solution of succinimide. The NBS product precipitates and can be collected by filtration. [1] Crude NBS gives better yield in the Wohl–Ziegler reaction. In other cases, impure NBS (slightly yellow in ...
It is a specialized reagent in organic synthesis.Combined with azobisisobutyronitrile (AIBN) or by irradiation with light, tributyltin hydride converts organic halides (and related groups) to the corresponding hydrocarbon.
N-bromosuccinimide (NBS), the bromine analog of N-chlorosuccinimide. [ 5 ] Other N -chloro compounds that are commercially available include chloramine-T , trichloroisocyanuric acid ((OCNCl) 3 ), 1,3-dichloro-5,5-dimethylhydantoin.
The relative rates at which different halogens react vary considerably: [citation needed] fluorine (108) > chlorine (1) > bromine (7 × 10 −11) > iodine (2 × 10 −22).. Radical fluorination with the pure element is difficult to control and highly exothermic; care must be taken to prevent an explosion or a runaway reaction.
The term nature-based solutions was put forward by practitioners in the late 2000s. At that time it was used by international organisations such as the International Union for Conservation of Nature and the World Bank in the context of finding new solutions to mitigate and adapt to climate change effects by working with natural ecosystems rather than relying purely on engineering interventions.
Niobium(V) chloride is the main precursor to the alkoxides of niobium, which find uses in sol-gel processing.It is also the precursor to many other Nb-containing reagents, including most organoniobium compounds.

Ether cleavage refers to chemical substitution reactions that lead to the cleavage of ethers.Due to the high chemical stability of ethers, the cleavage of the C-O bond is uncommon in the absence of specialized reagents or under extreme conditions.
