Used as a highly efficient catalyst in cross-coupling reactions, particularly in the formation of carbon-carbon bonds. It enables coupling under mild conditions with high selectivity, making it valuable in the synthesis of complex organic molecules, including pharmaceuticals and functional materials. Its stability and reactivity profile allow for low catalyst loadings and compatibility with a range of functional groups, reducing side reactions. Commonly applied in Negishi and Suzuki-type couplings where traditional catalysts may fail.
