摘要

Ferrocenyl Lawesson’s reagent (FcLR) or 2,4-diferrocenyl-1,3- dithiadiphosphetane 2,4-disulfide, which acts as a thionation reagent, is a groundbreaking organometallic compound that has been widely used in numerous fields, particularly in the architecture of novel organometallic compounds. Ferrocene (Fc) attached to a phosphorus-sulfur bond in FcLR is crucial for engineering these complexes. In other words, compared to traditional Lawesson’s reagent (LR) ligands, FcLR demonstrates superior reactivity and greater synthetic versatility, taking advantage of the exceptional properties of phosphorus and sulfur, while the distinctive characteristics of Fc can provide new opportunities in organometallic chemistry and lead to the creation of innovative Fc-containing structures. Here, we reviewed applications of FcLR in the synthesis of its salts, heterocycles, macrocycles, zwitterions, and metal complexes, as well as its utilization in thionation reactions. The categorization presented in this review is based on the reaction products. Finally, other special applications of FcLR and its derivatives are discussed, including their usage in electrochromic polymers, metallopolymers, biosensors, anti-microorganism agents, and dye-sensitized solar cells.
