Diversity of Lawesson's Reagent: Advances and Scope

Abstract Lawesson's reagent is a classic example of a compound having a remarkable construction and also a distinctive chemical behaviour that can challenge stereotype conceptual explanations. At the very beginning, it was mainly known for its use in the thionation of various types of carbonyl groups. However, over the last few years chemists reported some appealing examples which can nurture the chemistry community to perceive innovative ideas. These include the construction of valuable heterocycles, important coupling reactions, and the decoration of metal‐based attractive cores. Several important reports provided comprehensive theoretical studies regarding mechanistic classification. This article gives an overview of the recent insights and synthetic applications of this famous reagent from 2013 to 2019.
