▼a Our group developed CF2HSO2Cl as a CF2H radical source and this reagent is easily prepared in large quantities from cheap, readily available starting materials. CF2HSO2Cl, combined with a photoredox catalyst, proved to be an efficient method to |

▼a Using visible-light photoredox conditions, difluoromethylation and 1,1-difluoroalkylation of biphenyl isocyanides allowed the synthesis of a series of 6-(difluoromethyl)- and 6-(1,1-difluoroalkyl)phenanthridines via tandem addition/cyclization/o |

▼a A photo-redox catalyzed aminodifluoromethylation reaction of unactivated alkenes has been developed using HCF2SO2Cl as the HCF 2 radical source. Sulfonylamides were active nucleophiles in the cyclization processes to form pyrrolidines, and ester |

▼a A visible light-mediated difluoromethylation of N-benzylacrylamides with HCF2SO2Cl as the HCF2 radical precursor is described. The reaction incorporates a tandem cyclization/dearomatization process to afford various difluoromethylated 2-azaspiro |

▼a A photo-redox catalyzed difluoromethylation reaction of unactivated alkenes, coupled with C(sp2)-C(sp3) bond formation was established. It's the first example of introduction of the difluoromethyl group into the tetralin skeleton system. Further |
