Allylpalladium(II) chloride dimer
CAS 12012-95-2
[Pd(allyl)Cl]₂ is the highest-Pd-density soluble precatalyst platform — the dimer from which (allyl)Pd(L)Cl precatalysts are assembled in situ with your ligand of choice, and a classic Tsuji–Trost allylation catalyst in its own right.

Where [Pd(allyl)Cl]₂ is used
In-situ precatalyst assembly
Combined with bulky phosphines or NHC ligands, the dimer cleaves to give defined L·Pd(allyl)Cl species that activate rapidly — the economical route to modern precatalyst performance without buying named precatalysts.
Allylic substitution
A direct catalyst for Tsuji–Trost allylation of C-, N- and O-nucleophiles, widely used in complex-molecule synthesis and API route development.
Storage and shipping
Storage. Store cold (2–8 °C), sealed and dry; briefly air-stable during weighing.

Frequently asked questions
Why the highest Pd density among precatalysts?
At ≥58% Pd the dimer carries more palladium per gram than any phosphine complex, so freight, storage and metal accounting per mole of active catalyst are the leanest available.
How is pricing structured?
Quotes reference the day's metal fixing on assayed contained metal plus a stated conversion charge, and can be locked at order confirmation for recurring volumes.
Do you take back spent material?
Yes — spent catalyst, residues and off-spec lots are assayed on receipt and the recovered metal credited against your next order, closing the loop on your metal inventory.
