in particular, reactions based on the intermediate formation of benzynes. This report describes short sequences for the synthesis of various derivatives based on regioselective bromination, ortho-metalation, and halogen/metal permutations. 1,2-Dibromo-3-iodobenzene (2f), 1,2-dibromo-4-iodobenzene (4c), and 2,3-di-bromo-1,4-diiodobenzene (5e) act as intermediates in these syntheses.
