Photochemistry has ushered in a new era in the development of chemistry, and photoredox catalysis has become a hot topic, especially over the last fifteen years, with the combination of visible-light photoredox catalysis and radical reactions. Recently, visible-light photoredox catalysis has emerged as a powerful tool for the synthesis of densely substituted heterocycles that are difficult to prepare by traditional methods . All these features make photoredox catalysis a sustainable alternative from the viewpoint of radical reactions and one that can be utilized as an elegant method to access reactive radicals giving practically valuable heterocyclic derivatives. Despite the recent publication of several large reviews on the photochemical formation of C-S bonds , the topic of photochemical synthesis of 1,3-benzothiazoles is very poorly described. Considering our constant interest in sulfur-containing heterocycles and their chemistry , we have found that more than 20 different types of such S-heterocycles can be obtained photochemically, and among them, the benzothiazoles are definitely the most developed. They are privileged and versatile heterocyclic scaffolds with extensive applications in pharmaceutical industry and materials science. As of November 2024, Reaxys® database showed approximately 340k compounds mentioned in >196k documents related to chemical space of 1,3-benzothiazoles. There are several early works published in 1982 and 1997 using ultraviolet (UV)-light-induced intramolecular aromatic substitutions of 2-bromo/iodo-thiobenzanilides to benzothiazoles. The application of quartz equipment, highenergy UV light and harsh conditions (in some cases a strong base in liquid ammonia) limits the substrate scope and causes unwanted side reaction products. Since the first ground-breaking work in 2009 , we found only 56 papers where benzothiazole motif was directly formed through photochemical event using visible light and in most cases at room temperature (Fig. ). Thus, we believe this narrow area deserves separate consideration as a presented comprehensive review.
