| Outline of Final Research Achievements |
We have successfully synthesized a series of palladium complexes having a Z-type, group 13 metalloligand utilizing 6,6''-bis(phosphino)-2,2':6',2''-terpyridine derivatives as an efficient scaffold for M-E bonds (E = Al, Ga, In). Systematic investigation revealed unique characteristics of the Al-metalloligand in both structure and reactivity, which exhibited the highest catalytic activity for hydrosilylation of CO2 ever reported (TOF = 19300 h-1). We have also achieved synthesis of an Ir complex having a pincer-type gallylene ligand through the complexation-induced reduction of GaIII by IrI utilizing the N,P-multidentate ligand. The pincer-type structure enabled various reactions at Ir with keeping the gallylene ligand intact. Furthermore, we also demonstrated that the Ga-Rh complex can be an efficient catalyst for hydrosilylation of nitriles to imine oxidation level. This is a highly useful method for the synthesis of oximes from nitriles.
