Expeditious and Efficient ortho-Selective Trifluoromethane-sulfonylation of Arylhydroxylamines
A metal- and oxidant-free, practical and efficient method for the synthesis of highly versatile and synthetically useful ortho-trifluoromethanesulfonylated anilines from arylhydroxylamines and trifluoromethanesulfinic chloride was developed. This rapid tr
