A tunable decarboxylative trifluoromethylthiolation of cinnamic acids with AgSCF3 was developed to afford trifluoromethylthiolated alkenes or ketones by using transition metal‐mediated conditions.
Mild‐mannered sulfur: A general method for the synthesis of vinyl trifluoromethylthioethers starting from readily available di‐, tri‐, and tetrasubstituted vinyl iodides was developed (see scheme). A wide variety of substrates were applied in the reaction with CuSCF3 to give the corresponding products in high yields, within short reaction times, with retention of the initial E/Z isomer ratio. In addition
