A silver-promoted oxidative benzylic C-H trifluoromethoxylation has been reported for the first time. With trifluoromethyl arylsulfonate as the trifluoromethoxylation reagent, various arenes, having diverse functional groups, undergo trifluoromethoxylation of their benzylic C-H bonds to form trifluoromethyl ethers under mild reaction conditions. In addition, the trifluoromethoxylation and the fluorination of Me groups of electron-rich arenes have been achieved to prepare α-fluorobenzyl trifluoromethyl ethers in one step. In the experiment, the researchers used many compounds, for example, 1-Chloro-4-iodobutane (cas: 10297-05-9Reference of 10297-05-9).
1-Chloro-4-iodobutane (cas: 10297-05-9) belongs to iodide derivatives. Organoiodine compounds occur widely in organic chemistry, but are relatively rare in nature. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.Reference of 10297-05-9
