In this research, we uncovered properties of new chemical species "pyridylidene" and synthesized a new pyridylidene metal complex toward the application to catalytic reaction. First we successfully generated free pyridylidene and reacted it with several reagents. Moreover, decomposition pathway of pyridylidene was also found. Next we synthesized bidentate bis-2-pyridylidene palladium complex, which has very unique electronic and structural characters and moreover it can be synthesized only three steps from commercially available compounds easily. The synthetic method can also be applicable to other late transition metals so that establishment of new catalyst library utilizing high stability and donation ability of pyridylidene.
