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. <i>meta</i>- and <i>para</i>-dibromoarenes were converted via these intermediates into functionalized arylboronates in a one-pot manner.
