confirmed by X-ray crystallography. Complex Ru–Pd exhibits catalytic activities for the tandem reactions of Suzuki–Miyaura coupling/transfer hydrogenation of p-bromoacetophenone with phenylboronic acid in isopropanol, whereas Ir–Pd shows a moderate activity. However, complex Rh–Pd does not behave the same way. Furthermore, catalytic activity of these heterobimetallic complexes toward debromination/transfer
