Isopropoxide protection of arylboronates allowed their use in metal−halogen exchange reactions. The isopropoxide-protected borate species were obtained from a boronate or in situ from dibromoarenes. meta- and para-dibromoarenes were converted via these intermediates into functionalized arylboronates in a one-pot manner.
