In a coordinating solvent such as DMF, the fast oxidative addition of vinyl triflates to Pd0(PPh3)4 performed under stoichiometric conditions gives the cationic complexes [(η1-vinyl)Pd(PPh3)2(DMF)]+TfO-, which have been characterized by conductivity

The electrochemical reduction of aryl and vinyl triflates in the presence of CO2 and a catalytic amount of palladium results in the formation of aromatic and α,β-unsaturated carboxylic acids. Aryl and vinyl triflates usually undergo palladium-catal

Amines used as bases in copper-free, palladium-catalyzed Sonogashira reactions play a multiple role. The oxidative addition of iodobenzene with [Pd 0 (PPh 3 ) 4 ] is faster when performed in the presence of amines (piperidine > morpholine). Amines al

The rate constant of the oxidative addition of the benzoic anhydride (PhCO)2O to [Pd0(PPh3)4] has been determined in DMF and compared to that of phenyl halides and phenyl triflate. The following reactivity order has been established: PhI >> (PhCO)2O
