Suzuki reaction has become one of the most powerful synthetic tools in organic chemistry to construct the C(sp2)-C(sp2) bond. Unfortunately, many boronic acids bearing the electron-deficient heterocyclic substituents do not exist. Stannanes are more stable and can also undergo coupling reaction catalyzed with transition metals.
Properties
- readily prepared, purified and stored
- compatible with a wide range of functional groups
- mild reaction conditions
- not sensitive to moisture in Stille coupling
Reactivity
Stille reaction runs selectively in the presence of the active chlorine atoms.
