Synthesis and Reactivity of Six-Membered Cyclic Diaryl λ³-Bromanes and λ³-Chloranes

We have developed a synthetic strategy for accessing wide range of hypervalent bromine(III) and chlorine(III) reagents. The unique structural pattern and high reactivity of those molecules can be useful for room temperature O- and S- arylation, intra- and inter- molecular biaryl formation depending on reaction conditions. The characterisation data set contains 1H, 13C, DEPT 135, 19F, HRMS and Crystal XRD for the synthesised compounds.An appropriate processing software is required for raw NMR data files, HRMS and Crystal data files.
