Synthesis and characterization of some cationic eta3-propargylpalladium complexes
Some cationic eta3-propargylpalladium complexes were prepared upon treatment of the corresponding eta1-propargyl- or eta1- allenylbis(triphenylphosphine)palladium(II) chloride with Ag[BF4] or Na[BPh4]. The effectiveness of the latter reagent suggests that a eta1- propargyl- or eta1-allenyl(chloro)palladium complex equilibrates with a cationic eta3-propargylpalladium complex with the liberation of a Cl- ligand. A qualitative comparison of trends in a series of analogous equilibrium systems suggests that the eta3-coordination mode is favored to a greater extent when (i) propargyl ligands have an alkyl substituent at the propargylic position, (ii) phosphine ligands are bidentate, such as dppe, (iii) polar solvents are used, and (iv) the liberating ligand is a Cl- one. A possible implication of eta3-coordination of propargyl ligands in a catalytic cycle of Pd-catalyzed transformations of propargylic or allenylic substrates is presented.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 2926-30-9
