4923-87-9, Research speed reading in 2021. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative theoretical assessments of solvent structures. In a article, 4923-87-9, molcular formula is C8H5BrS, introducing its new discovery.
Using triphenylmethylium tetrakis(pentafluorophenyl)borate as a convenient Br°nsted 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.
