A comparative study of the advantages of using THF compared with DMF in regioselectivemonobromination reactions of highly activated polyphenols, their ethers, and their tert-butyl carbonate derivatives under mild conditions is described. Bromination with the common reagent N-bromosuccinimide in polar solvents provided an easy and fast approach to aromatic electrophilic substitution at the most electronically

development of alternative methods to access arynes using simpler substrates and milder conditions is necessary for a more streamlined approach. Here, we describe a two-step formal dehydrogenation of simple arenes to generate arynes at a remote position relative to traditionally reactive groups, e.g., halides. This approach is enabled by regioselective installation and ejection of an “onium” leaving group, and
