4923-87-9, In an article, published in an article,authors is Cai, Xiao, once mentioned the application of 4923-87-9, Name is 5-Bromobenzothiophene,molecular formula is C8H5BrS, is a conventional compound. this article was the specific content is as follows.
Br¡ãnsted Acid-Catalyzed Intramolecular Hydroarylation of beta-Benzylstyrenes
Using triphenylmethylium tetrakis(pentafluorophenyl)borate as a convenient Br¡ãnsted acid precatalyst, beta-(alpha,alpha-dimethylbenzyl)styrenes are shown to cyclize efficiently to afford a variety of new indanes that possess a benzylic quaternary center. The geminal dimethyl-containing quaternary center is proposed to be necessary to arm the substrate for cyclization through steric biasing.
