摘要：

A new decarbonylation reaction is observed for [(K-2-acetate) Pd(K-2-diphosphine)](+) complexes. Gas-phase IR experiments identify the product as [CH3Pd(OP(Ph-2) CH2PPh2)](+). DFT calculations uncovered a plausible mechanism involving O atom abstraction by the diphosphine ligand within the coordination sphere to yield the acetyl complex, [CH3COPd(OP(Ph-2) CH2PPh2)](+), which then undergoes decarbonylation.
