Computed Properties of C4H2Br2SIn 2021 ,《Steering Scholl Oxidative Heterocoupling by Tuning Topology and Electronics for Building Thiananographenes and Their Functional N-/C-Congeners》 was published in Chemistry – A European Journal. The article was written by Maddala, Sudhakar; Panua, Anirban; Venkatakrishnan, Parthasarathy. The article contains the following contents:
This report systematically demonstrates how topol. variation of electronics and reactivity in thiophene substrates can lead to efficient oxidative heterocoupling. Bis(biaryl)thiophenes having reactive α- and β-positions open are the choice of substrates. The cyclizing arene partners are so electronically tuned for thiophene’s reactivity (at α- and β-) as to establish C-C bond oxidatively generating sym. as well as unsym. diphenanthrothiophenes which are basic thiananographenes. Depending on the cyclizing-couple’s electronics, either arene- or thiophene-centered oxidation initiates C-C heterocoupling. The potential utility of these simple thiananographenes is further unfurled by converting them to functional N-/C-graphene segments that are aza-corannulene precursor and tetrabenzospirobifluorene. Their bright emission and extended electrochem. stability are remarkable that may be potentially important and applicable. The results came from multiple reactions, including the reaction of 2,5-Dibromothiophene(cas: 3141-27-3Computed Properties of C4H2Br2S)
2,5-Dibromothiophene(cas: 3141-27-3) , is mainly used as pharmaceutical intermediate and synthesis intermediate. 2,5-Dibromothiophene polymerizes by debromination with magnesium catalyzed by nickel compounds to form poly(2,5- thienylene) .Computed Properties of C4H2Br2S
