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

<p dir="ltr">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. </p><p dir="ltr">The characterisation data set contains 1H, 13C, DEPT 135, 19F, HRMS and Crystal XRD for the synthesised compounds.</p><p dir="ltr">An appropriate processing software is required for raw NMR data files, HRMS and Crystal data files.</p>
