The most common organic halides used as starting materials in the Suzuki reaction are aryl and vinyl halides.

Explanation:

The Suzuki reaction, also known as the Suzuki-Miyaura cross-coupling reaction, is a widely used method in organic chemistry for forming carbon-carbon bonds. This reaction typically involves the coupling of an aryl or vinyl boronic acid with an organic halide in the presence of a palladium catalyst and a base.

Aryl halides, which consist of a halogen atom bonded to an aromatic ring, are prevalent due to their stability and the ability to participate effectively in cross-coupling reactions. Vinyl halides, which contain a halogen atom attached to a vinyl group (an alkene), also play a crucial role because they can create alkenes with specified geometric isomers when coupled.

Both types of halides are favored starting materials as they react well with boronic acids under appropriate reaction conditions, leading to desired products in a variety of synthetic applications.
