摘要

Abstract 1, 2-Dibromobenzenes are highly valuable precursors for various organic transformations, 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-dibromo-1, 4- ...
