Our group has initiated a program to study fundamental organometallic reactivities using structurally well-defined molecular systems. In this talk, we will present our recent findings on:
(1) activation of functionalized alkynes for new coordination complexes (including metal-indoline, -indole-zwitterion, -indolizine-zwitterion complexes and metallafurans),
(2) development of new nitrosoarene-derived non-innocent ligand systems, and
(3) photophysics of several classes of ruthenium and osmium complexes bearing N-heterocyclic carbene-derived auxiliary ligands, and their biological applications.
