Wiredu, Bernard; Thapa, Mahendra; Hua, Sheen Y.; Desper, John; Hua, Duy H. published an article in 2021. The article was titled 《Synthesis of 2,24-Diene-12,13,15,16,34,35,37,38-octaphenyl[4.4]triphenylparacyclophane》, and you may find the article in Synthesis.Safety of 1,4-Bis(bromomethyl)benzene The information in the text is summarized as follows:
A new octaphenyl[4.4]triphenylparacyclophanediene was readily synthesized in six steps from p-xylene via the installment of bromine atoms, replacement with a vinyl group, carbonylative coupling, intermol. followed by intramol. double Grubbs olefin metathesis, Knoevenagel condensation and Diels-Alder cycloaddition The belt-shaped structure and trans-stereochem. of the alkene moieties of the octaphenyl[4.4]triphenylparacyclophane and a synthetic intermediate, 2,21-dioxo-11,30-diene[3.4.3.4]paracyclophane, were determined by X-ray crystallog. The synthetic methodol. leading to octaphenyl[4.4]triphenylparacyclophane was applicable for the synthesis of substituted triphenylparacyclophanes and possibly their corresponding bis-hexabenzocoronenylparacyclophanes via a Scholl-Mullen oxidative aryl-aryl coupling reaction. In the experiment, the researchers used 1,4-Bis(bromomethyl)benzene(cas: 623-24-5Safety of 1,4-Bis(bromomethyl)benzene)
1,4-Bis(bromomethyl)benzene(cas: 623-24-5) belongs to organobromine compounds.Organobromine chemicals are produced naturally by an array of biological and other chemical processes in our environment. Safety of 1,4-Bis(bromomethyl)benzeneSome of these compounds are identical to man-made organobromine compounds, such as methyl bromide, bromoform, and bromophenols, but many others are entirely new moleclar entities, often possessing extraordinary and important biological properties.
