A carbon-13 NMR investigation of [5]metacyclophanes was written by Jenneskens, L. W.;De Kanter, F. J. J.;De Wolf, W. H.;Bickelhaupt, F.. And the article was included in Magnetic Resonance in Chemistry in 1986.COA of Formula: C8H8Br2 This article mentions the following:
13C NMR data of [5]metacyclophane, its 8,11-dihalosubstituted derivatives and of some model compounds are reported and discussed. A remarkable downfield shift is observed for the aromatic carbon between the bridging carbons; this is tentatively ascribed to long-range effects of the bridge and to the bending of the aromatic ring. In the experiment, the researchers used many compounds, for example, 2,5-Dibromo-1,3-dimethylbenzene (cas: 100189-84-2COA of Formula: C8H8Br2).
2,5-Dibromo-1,3-dimethylbenzene (cas: 100189-84-2) belongs to organobromine compounds. Organo bromine compounds are versatile compounds and are widely used in diverse fields. Organo bromine derivatives are used in the dye sector, as an indicator in analytical chemistry (Bromothymol blue is a popular indicator). One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.COA of Formula: C8H8Br2
