Initial investigation into the Suzuki–Miyaura vinylation of hindered aryl bromides utilizing potassium vinyltrifluoroborate

An initial study of the Suzuki–Miyaura cross-coupling of potassium vinyltrifluoroborate (2) and hindered aryl bromides is presented. Coupling of benzyl 3,5-bis(benzyloxy)-4-bromobenzoate (1) leads to a mixture of the desired styrene derivative, and the reduced product.
