Palladium-catalyzed reactions are chemical processes that use palladium, a precious metal, as a catalyst to facilitate various transformations. These reactions are essential in organic chemistry for forming carbon-carbon and carbon-heteroatom bonds, making them valuable in synthesizing complex molecules, including pharmaceuticals and agrochemicals. One of the most common types of palladium-catalyzed reactions is the Suzuki coupling, which allows for the joining of two organic groups through a palladium catalyst. Other notable reactions include Heck reaction and Stille coupling, each contributing significantly to the development of new materials and compounds in research and industry.
