Diacetoxyiodobenzene (PhI(OAc)2), commonly referred to as DAIB or phenyliodine(III) diacetate (PIDA), is one of the most frequently used hypervalent iodines employed as an oxidizing agent in organic chemistry. In this review, PIDA is highlighted exclusively in relation to its applications in organic synthesis involving heterocyclic ring formations and is critically and in‐depth examined from the summer of 2015 to the present with a specific focus on the mechanistic pathway.

During the past few years, single‐atom catalysts (SACs) have attracted considerable attention in electrolysis due to their outstanding catalytic performance and efficient atomic utilization. SACs exhibit a simple structure, high catalytic activity, consistent scaling relationships for single sites, and low metal content but their practical applications are still limited. Dual single‐atom catalysts (DACs), which feature excellent selectivity, high atomic utilization efficiency, and remarkable stability, are emerging as new frontiers in heterogeneous electrocatalysis. They increase catalytic activity by promoting synergistic effects between metal‐active sites. In this paper, we present a comprehensive overview of the latest developments in dual‐atom catalysts for oxygen evolution reaction (OER) and oxygen reduction reaction (ORR). In addition, we explore the differences between homonuclear and heteronuclear configurations, the emergence of single/dual‐site metal catalysts, and the methods currently used for their synthesis. Lastly, this review discusses several perspectives for advancing the development of dual‐atom catalysts for OER and ORR electrocatalysis. [ABSTRACT FROM AUTHOR]

One of the most often utilized hydroperoxides in an array of oxidation strategies is tert‐butyl hydroperoxide (tBuOOH, TBHP). The key reasons for rising utility of TBHP are its low cost, environmental friendliness, high efficiency, and ability to replace hazardous or rare heavy metal oxidants. In this sexennial update, we concisely and critically discussed the applications of TBHP in heterocyclic ring formations starting from 2018 to date. Merits and demerits of its utility, scope of a synthetic organic transformation along with mechanistic logistics are the key features of this review. [ABSTRACT FROM AUTHOR]

Although the first synthesis of benzotriazole was performed in the 19th century still new methods for their preparation have developed. In this micro review authors focus mostly on the various synthetic strategies developed so far to synthesize benzotriazole and its derivatives by different strategies, such as metal‐free, metal‐assisted [3 + 2] cycloaddition reactions, cyclocondensations, flow methods, heterocyclizations, and so forth. This micro review combines recent (2005–2022 till date) information on the strategies used for the synthesis of benzotriazoles. Moreover, a brief overview of the bio applications of the benzotriazole scaffold along with pharmacological activity is also discussed. [ABSTRACT FROM AUTHOR]
