Boronic acids, esters and borinic anhydrides are partners in Suzuki–Miyaura cross-coupling reactions with a variety of β-chlorovinamidinium salts to give the desired β-arylvinamidinium salts in up to 88% yield. Reduction is a competing reaction pathway. DFT calculations on the intermediate palladium complex reveal that the Pd–C interaction is predominantly of σ-symmetry and the metal based LUMO is...
