interaction resulted in the formation of a pseudo-octahedral geometry with the iridium center. The iridium complexes 1–4, which are stable in the presence of air and moisture, exhibit significant catalyst performance in the N-alkylation reactions of hydrazides under gentle reaction conditions. This iridium complex catalyzes various types of alcohols to undergo N-alkylation reactions with acyl hydrazides via a
