Bis[tris(2-methylphenyl)phosphine]palladium
Bis[tris(2-methylphenyl)phosphine]palladium (CAS 69861-71-8; C42H42P2Pd; molar mass 715.15 g/mol) is a homogeneous palladium(0) complex bearing two tri(o-tolyl)phosphine ligands, also written Pd[P(o-tol)3]2. Supplied as a defined-assay organometallic solid, it is a versatile pre-catalyst for palladium-catalysed cross-coupling chemistry, including Kumada and Heck couplings, arylations and aminations. Tech Serve Solutions supplies it as a research-grade catalyst to laboratory and fine-chemical customers worldwide.

Cross-coupling catalysis
Acts as a palladium(0) source for a broad range of palladium-catalysed cross-coupling reactions used to form carbon-carbon and carbon-heteroatom bonds. The bulky tri(o-tolyl)phosphine ligands make it a useful pre-catalyst for demanding couplings.
Kumada coupling
Used to catalyse Kumada cross-couplings between organomagnesium (Grignard) reagents and organic halides, providing access to biaryls and substituted arenes in synthetic chemistry.
Heck coupling
Serves as a catalyst for Mizoroki-Heck reactions, coupling aryl or vinyl halides with alkenes to build substituted olefins commonly required in fine-chemical and intermediate synthesis.
Arylation
Employed in palladium-catalysed arylation reactions to introduce aryl groups onto organic substrates, supporting the preparation of advanced intermediates and building blocks.
Buchwald-Hartwig amination
Functions as a catalyst for palladium-catalysed amination, forming carbon-nitrogen bonds between aryl halides and amines en route to anilines and related nitrogen-containing structures.
