Coupling mechanism

One difference between the Suzuki mechanism and that of the Stille Coupling is that the boronic acid must be activate for example with base. Coupling is defined as the means by which a magnetic or electric field produced by a circuit induces a voltage or current in another circuit. Electro-magnetic acoustic transducers (EMATs) generate ultrasonic waves in metals through an electromagnetic coupling mechanism.
