摘要：
Boronic acids, esters and borinic anhydrides are partners in Suzuki-Miyaura cross-coupling reactions with a variety of beta -chlorovinamidinium salts to give the desired beta -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 a-symmetry and the metal based LUMO is mainly d(z2) in character.
