in tandem at the carbene center to install an electrophile and a nucleophile on the same carbon. This metal-free concept, which is unprecedented, has been illustrated by regioselectivesynthesis of a variety of vinyl halides, vinyl sulfones, and alkyne derivatives.
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
