Azole and azine heteroarenes were directly alkylated by alkanes, ethers, or carbamates using PhC(O)O2tBu under LED irradiation. 9,10-Dichloroanthrocene acted as an organic photocatalyst and transferred its excitation energy to PhC(O)O2tBu via exciple

The development of high-performance blue organic light-emitting diodes (OLEDs) remains a challenging task. While exploiting new blue emitters has attracted great interest, developing host materials that considerably determine device performance obvio

A nickel complex of isoquinox promoted enantioselective conjugate arylation and heteroarylation of enones using aryl and heteroaryl halides directly. The reaction was successfully applied to stereoselective syntheses of ar-turmerone, chiral fragments

We herein illustrate the dual chelation-assisted strategy for a Ru(II)-catalyzed oxidative ortho-C–H/C–H cross-coupling of phenols with (hetero)aromatic amides with the aid of Zn(OTf)2, which enables to rapidly assemble a rich library of 2′-hyd

By making use of a dual-chelation-assisted strategy, a completely regiocontrolled oxidative C-H/C-H cross-coupling reaction between an N-acylaniline and a benzamide has been accomplished for the first time. This process constitutes a step-economic an

The directed oxidative C-H/C-H cross-coupling reactions between a functionalized arene and a heteroarene typically exhibit an electronic bias for the heteroaromatic coupling partner. Disclosed herein is a conception of directing group enabled-switchi
