Herein, we have developed a metal‐free and mild condition for the synthesis of 2‐arylated heteroarenes. The complex forming property and charge transfer property of phenothiazine expanded its application towards catalysis The optimized condition has been successfully employed for the synthesis important marine natural product namely pentabromo/chloropseudilins (PBP/PCP). The synthesized Pentachloropseudilin
Photo-involving aryl halide activation plays a pivotal role in organic synthesis and materials science. Revealing the mechanism and understanding the photophysical and photochemical processes in the activation is of great importance. Here, we found that aryl halides could be directly activated to form aryl radicals via halogen bonding under visible light irradiation without using photocatalysts or
