Visible-light-mediated radical arylthiodifluoromethylation of isocyanides with fluorinated 2-pyridyl sulfones†
Abstract
A novel class of shelf-stable and easily scalable arylthiodifluoromethyl 2-pyridyl sulfone derivatives was developed as powerful arylthiodifluoromethylation reagents, which allow efficient radical arylthiodifluoromethylation of various isocyanides to form phenanthridines and isoquinolines in good to excellent yields.
