The present invention relates to a method for producing a lactam compound from dioxazolone in the presence of a catalyst having a particular ligand, and to a lactam compound produced thereby, and can produce a lactam compound with excellent selectivity and an excellent yield by using the combination of a starting material having a particular functional group and a particular catalyst having a particular ligand.

site-selectivity is highly desirable especially in C-H functionalization reactions. We report a new catalyst platform that is highlyselective for the amidation of benzylic C-H bonds controlled by π-π interactions in the secondary coordination sphere. Mechanistic understanding of the previously developed iridium catalysts that showed poor regioselectivity gave rise to the recognition that the π-cloud
