《Trifluoromethyl Sulfoxides: Reagents for Metal-Free C-H Trifluoromethylthiolation》 was published in Angewandte Chemie, International Edition in 2020. These research results belong to Wang, Dong; Carlton, C. Grace; Tayu, Masanori; McDouall, Joseph J. W.; Perry, Gregory J. P.; Procter, David J.. Recommanded Product: 5-Bromobenzo[d][1,3]dioxole The article mentions the following:
Indoles, pyrroles, thiophenes, a benzothiophene, a benzofuran, and arenes underwent metal-free regioselective trifluoromethylthiolation with trifluoromethyl sulfoxides RCH2S(:O)CF3 (R = Ph, EtO2C) mediated by triflic anhydride and diethylamine in acetonitrile or nitromethane to yield heteroaryl and aryl trifluoromethyl thioethers. An aryl(ethoxycarbonylmethyl)(trifluoromethyl)sulfonium triflate was isolated as a trifluoromethylthiolation intermediate and its structure determined by X-ray crystallog., supporting an interrupted Pummerer reaction mechanism for the trifluoromethylthiolation. In the experiment, the researchers used 5-Bromobenzo[d][1,3]dioxole(cas: 2635-13-4Recommanded Product: 5-Bromobenzo[d][1,3]dioxole)
Furthermore, the coupling of 5-Bromobenzo[d][1,3]dioxole(cas: 2635-13-4) with β-methallyl alcohol was catalyzed by Pd(OAc)2 in combination with P(t-Bu)3.Recommanded Product: 5-Bromobenzo[d][1,3]dioxole
