Bis(dibenzylideneacetone)palladium(Cat No.: R045426), abbreviated as Pd(dba)₂, is a dark-purple organopalladium complex widely used as a precatalyst in cross-coupling reactions such as Suzuki, Heck, and Sonogashira couplings. With the formula Pd(C₁₇H₁₄O)₂, it features two dibenzylideneacetone ligands coordinated to a central palladium atom. Its air-stable, soluble nature in organic solvents makes it valuable in homogeneous catalysis. Pd(dba)₂ facilitates efficient C–C bond formation in organic synthesis, particularly in pharmaceutical and fine chemical development. It requires careful handling due to sensitivity to air and moisture.
