15 Σεπ 2021 · This review systematically summarizes different methods in developing SmI 2 catalyzed reactions. Current challenges and possible future directions are also presented.
This paper presents the effect of additives on the mechanism and selectivity of the SmI2-mediated coupling of alkyl halides and ketones. The reaction of 1-iodobutane and 2-octanone was carried out with SmI2 in the absence of cosolvent and in the presence of HMPA, LiBr, and LiCl.
24 Μαρ 1997 · This paper reports a successful solution of this problem for three of the most interesting applications of SmI2: (1) annulation of ketones to T-lactones using acrylate esters, (2) SmI2 initiated radical cyclization of unsaturated iodides and (3) deoxygenation of oxiranes to form olefins.2 We have not studied pinacol couplings because several ...
Substrate-Directable Electron Transfer Reactions. Dramatic Rate Enhancement in the Chemoselective Reduction of Cyclic Esters Using SmI2–H2O: Mechanism, Scope, and Synthetic Utility. Journal of the American Chemical Society 2013, 135 (42) , 15702-15705. https://doi.org/10.1021/ja4078864
This microreview provides an overview of the current knowledge of the reagent SmI2 as a reducing agent, in particular with additives that increase its reactivity. The use of various proton sources is covered, as well as the effect of co‐solvents.
1 Μαρ 2019 · It is demonstrated that the catalytic use of electrogenerated samarium diiodide (SmI2) could promote, in one-step synthesis, the reduction of nitrobenzenes into azobenzenes in high yields under mild reaction conditions, making this catalytic procedure a serious alternative to currently available methods.
