Gao, Yong-Chao published the artcileSulfite-Promoted C-H Fluoroalkyl Sulfuration of Imidazoheterocycles with Bromofluoroacetate and Elemental Sulfur, SDS of cas: 401-55-8, the publication is Synthesis (2020), 52(17), 2541-2550, database is CAplus.
A transition-metal-free sulfite-promoted three-component C-H sulfuration between imidazoheterocycles, elemental sulfur and bromofluoroacetate was developed. Sulfites, including Na2S2O4, NaHSO3 and Na2S2O3, were able to promote the formation of two C-S bonds in one step using elemental sulfur as a green sulfurating agent, allowing the rapid introduction of the synthetically useful S-fluoroacetate group into imidazoheterocycles. These new imidazoheterocycle derivatives bearing an S-fluoroacetate group can be easily modified to produce pharmaceutically attractive compounds
