Cross-coupling reaction

A cross-coupling reaction is a chemical process where two different organic molecules, usually containing halogens or other functional groups, are joined together using a metal catalyst, often palladium. This method allows chemists to efficiently build complex molecules, such as pharmaceuticals or plastics, by forming new carbon-carbon bonds. Think of it as a precise molecular handshake where two different partners are connected through a catalyst that facilitates the bonding, enabling the creation of larger, more intricate compounds from simpler building blocks in a controlled and efficient manner.
