1,1′-Bis[bis(1,1-dimethylethyl)phosphino]ferrocene（Cat No.:L020656）, commonly abbreviated as dtbpf, is a bulky, electron-rich bidentate diphosphine ligand derived from ferrocene. It features two di-tert-butylphosphino groups attached at the 1 and 1′ positions of the ferrocene backbone, providing a rigid, symmetrical framework with substantial steric hindrance. This ligand is widely used in coordination and organometallic chemistry, particularly in palladium- and nickel-catalyzed cross-coupling reactions such as Suzuki, Stille, and Negishi couplings. Its strong electron-donating properties enhance catalyst stability and activity, making it valuable in the synthesis of complex organic molecules and pharmaceuticals.
