Platinum-Catalyzed Phenyl and Methyl Group Transfer from Tin to Iridium:  Evidence for an Autocatalytic Reaction Pathway with an Unusual Preference for Methyl Transfer

Platinum complexes have been found to catalyze the transfer of σ-bound ligands to the Ir center in Cp*(PMe3)IrCl2 (Cp* = η5-C5Me5) from Bu3SnPh and Ph x SnMe4 - x (x = 0−3) complexes. Despite the presence of Sn−Ph bonds in the Ph x SnMe4 - x complexes, exclusive transfer of the Sn−Me group occurs, a...

Description
Summary:Platinum complexes have been found to catalyze the transfer of σ-bound ligands to the Ir center in Cp*(PMe3)IrCl2 (Cp* = η5-C5Me5) from Bu3SnPh and Ph x SnMe4 - x (x = 0−3) complexes. Despite the presence of Sn−Ph bonds in the Ph x SnMe4 - x complexes, exclusive transfer of the Sn−Me group occurs, an unusual chemoselective process. Examination of the reaction mechanism supports an autocatalytic process.
