Abstract There has been a persistent impetus for the development of versatile C−H functionalization reactions, which represents powerful approach to wide variety valuable chemical compounds. Transition metal catalyzed attracted intense interest and witnessed considerable advances in this field owing its outstanding regioselectivity atom‐economy. In recent years, rare‐earth (RE) metal‐based catalysts have successfully employed flourished area, demonstrating unique selectivity complementary reactivity with respect late‐transition metal‐catalyzed functionalization. The by taking advantage these characteristic properties is great importance interest. Herein, panorama during last decade presented.

Hydroxyl-Directed Rh(III)-Catalyzed C–H Functionalization: Access to Benzo[de]chromenes

Organic Letters, Journal Year: 2023, Volume and Issue: 25(10), P. 1622 - 1627

Published: March 3, 2023

A cascade oxidative annulation reaction of heterocyclic ketene aminals (HKAs) with internal alkynes catalyzed by [Cp*RhCl2]2 and oxidized Cu(OAc)2·H2O was developed to efficiently synthesize highly functionalized benzo[de]chromene derivatives in good excellent yields. The proceeded the sequential cleavage C(sp2)-H/O-H C(sp2)-H/C(sp2)-H bonds. These multicomponent reactions were regioselective. In addition, all products exhibited intense fluorescence emission solid state, they demonstrated concentration-dependent quenching presence Fe3+, indicating that these compounds could be used recognition Fe3+.
