Unexpected reaction pathway during the palladation of 2,5-diphenylphosphacymantrene

A new reaction of P-alkoxypalladation was found. 2,5-Diphenylphosphacymantrene reacts with Na2PdCl4 and NaOAc in MeOH or EtOH to give P-methoxy or P-ethoxy derivatives with Pd2Cl2 dimeric core. The products 2 and 3 were characterized by 1H, 31P, 13C NMR spectra and X-ray crystal structure data.
