Application of 955959-84-9, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 955959-84-9, name is 4-(4-Bromophenyl)dibenzo[b,d]furan belongs to bromides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
In an argon atmosphere, in a three-necked 100mL flask, compound (x) 0.8g, the compound (xi) 0.54g, bis(dibenzylideneacetone)palladium (0) (Pd(dba)2) 0.06g, tri-t-butylphosphine ((t-Bu)3P) 0.12g, was added to sodium t-butoxide 0.3g, was heated under reflux for 7 hours in 30mL of toluene solvent. After air-cooling, water was added The organic layer was separated, and the solvent was distilled off. The crude product thus obtained was purified by silica gel column chromatography (dichloro methane and using a mixed solvent of hexane) was subjected to recrystallization with toluene and hexane mixture solvent to give the compound A-35 as a white solid 0.95g (80percent yield)
The synthetic route of 4-(4-Bromophenyl)dibenzo[b,d]furan has been constantly updated, and we look forward to future research findings.
