We describe an efficient protocol for the Suzuki–Miyaura synthesis of ortho- biphenyltetrazoles from non-protected 2-bromophenyltetrazole and arylboronic acids. The optimised conditions were achieved using [1, 1′-bis (diphenylphosphino) ferrocene] dichloropalladium (II) as catalyst and Na2CO3 as base. A panel of structurally diverse arylboronic acids was used to demonstrate the scope of the coupling procedure.
