Palladium compounds are chemical substances that contain the element palladium, a precious metal known for its catalytic properties. These compounds are often used in various industrial applications, including electronics, jewelry, and automotive catalytic converters, where they help reduce harmful emissions. In addition to their industrial uses, palladium compounds play a role in organic chemistry, particularly in cross-coupling reactions. These reactions enable the formation of carbon-carbon bonds, making them valuable in the synthesis of pharmaceuticals and other complex organic molecules.
