Use of in situ isopropoxide protection in the metal-halogen exchange of arylboronates.
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.
