Abstract Herein, we report that bulky alkylphosphines such as P t Bu 3 can switch the roles from actor to spectator ligands promote FeCl 2 ‐catalyzed N ‐amidation reaction of arylamines with dioxazolones, giving hydrazides in high efficiency and chemoselectivity. Mechanistic studies indicated phosphine could facilitate decarboxylation dioxazolones on Fe center, hydrogen bonding interactions between nitrenoid intermediates might play a role modulating delicate interplay ligand, arylamine, acyl nitrene N, favoring N−N coupling over N−P coupling. The new ligand‐promoted protocols offer convenient way access various challenging triazane compounds via double or sequential primary arylamines.

Investigations into C-H amidation reactions catalysed by cationic half-sandwich d6 metal complexes revealed that the indenyl-derived catalyst [Ind*RhCl2 ]2 significantly accelerated directed ortho of benzoyl silanes using 1,4,2-dioxazol-5-ones. Ring slippage involving a haptotropic η5 to η3 rearrangement indenyl complex proposedly enables ligand substitution at centre proceed via associative, rather than dissociative pathways, leading significant rate and yield enhancements. Intriguingly, this phenomenon appears specific for weakly coordinating carbonyl-based directing groups with no acceleration observed corresponding strongly nitrogen-based groups.
