The development and utilization of reusable base-metal catalysts is a central topic in catalysis. Herein, via a catalyst design strategy, we present the preparation of a highly dispersed and acid-resistant subnanometer cobalt catalyst (<1 nm) by a MOF-templated method, which has been utilized for selective C–H oxidative sulfonylation of tetrahydroquinoxalines with odorless sodium sulfinates. The transformation enables generation of a variety of sulfonylquinoxalines with the merits of good substrate and functional group compatibility, high regio- and chemoselectivity, and the use of a naturally abundant and reusable metal catalyst. The work presented offers the potential for further design of heterogeneous nanocatalysts and fabrication of fu...
