This paper summarizes the recent developments of intramolecular orthopalladation of N - donor ligands including Schiff bases, diazo - compounds, amidines, hydrazones, oximes, heterocyeles, Some factors, such as palladium reagents, the structures of substrates, solvents and the size of C - Pd ring, which influence the ease of cyclopalladation are elucidated and the methanisms of different types of cyclopalladations are discussed. The application of some cyclopalladated compounds in organic synthesis are also reviewed.

Key words: ORGANONITROGEN COMPOUNDS, PALLADIUM COMPOUNDS, LIGANDS
