Borylation Reagents

The Miyaura borylation reaction is a powerful tool for the synthesis of boronates via cross-coupling of borylation reagents with aryl and vinyl halides. Borylated products can easily be purified by chromatographic techniques and are air stable. Strong activation of the product may enable the competing Suzuki coupling, so properly choosing an appropriate base is crucial for the success of the borylation reaction.

Most commonly, lithium or Grignard reagents are used in combination with an electrophilic source of boron to create C–B bonds. However, due to the highly nucleophilic and basic nature of the metal species in this two-step procedure, various functional groups are not well tolerated. The mild reaction conditions of the borylation reaction allow the preparation of boronates which are not accessible via lithium or Grignard intermediates.
