1-(Bromomethyl)-4-fluoro-2-nitrobenzene (cas: 76437-44-0) belongs to organobromine compounds. Many of the organo bromine compounds are relatively nonpolar. Bromine is more electronegative than carbon (2.8 vs 2.5) and hence the carbon in a carbon闁艰京鐗梤omine bond is electrophilic in nature. Bromine-containing agents predominate because not only are they more efficient than similar chlorine-containing species, but also the high atomic weight of bromine ensures that it is present in a high mass fraction within most organobromine compounds.Application of 76437-44-0

Cu2+ ion crosslinked carboxymethylcellulose/diatomite composite beads as an efficient catalyst for CuAAC reactions was written by Zeng, Fang;Zhang, Mingjuan;Li, Yiqun. And the article was included in Polymers for Advanced Technologies in 2021.Application of 76437-44-0 This article mentions the following:

Cu2+-crosslinked CM-cellulose/diatomite composite beads (CuII@CMC/DE) were prepared in simple and efficient way using ionic crosslinking techniques. In CuII@CMC/DE beads, diatomite serves as a reinforcing filler, and divalent copper cation acts as crosslinking agent. The chem. structure and morphol. of as-fabricated CuII@CMC/DE beads were well characterized using various techniques such as ICP, FT-IR, XRD, SEM, EDS, elemental mapping, TEM, XPS, and TGA. The CuII@CMC/DE beads exerted superior catalytic performance in CuAAC reactions of benzyl halides, sodium azide, and alkynes to yield regioselective 1,4-disubstituted-1,2,3-triazoles in excellent yields under green conditions. In these resultant catalytic composite beads, Cu2+ was used not only as a crosslinking agent but also as a metal catalyst for CuAAC reaction. The composite beads can be easily separated by filter and reused at least four times without any significant decrease on its activity and selectivity. In the experiment, the researchers used many compounds, for example, 1-(Bromomethyl)-4-fluoro-2-nitrobenzene (cas: 76437-44-0Application of 76437-44-0).
