Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it.

In organic chemistry, discovering new reactions is one thing, but to carry them off efficiently is quite another. Carbon-carbon bond-forming is at the heart of organic synthesis, allowing us to stitch.
