A regioselective intermolecular carbohalogenation of alkynes with alkenyl bromides enabled by dual photoredox and nickel catalysis is described. This dual protocol enables an atomeconomic access to a wide array of brominated 1,3dienes from simple starting materials. Broad substrate scope and high regioselectivity are observed. The synthetic utility has been demonstrated and preliminary mechanistic studies have been performed to elucidate the reaction pathway.

In this paper, we designed and synthesized a novel pH and NIR light responsive UCNPs/ TiO2/ Cur@ZIF-8 nano-composite. The newly synthesized nano-platform was characterized using the spectroscopic methods. Here, upconversion...
