On December 9, 2009, Sousa, Sara C. A.; Fernandes, Ana C. published an article.Formula: C17H19N3O2S The title of the article was Highly efficient and chemoselective reduction of sulfoxides using the system silane/oxo-rhenium complexes. And the article contained the following:
This work reports a novel method for the reduction of sulfoxides with silanes catalyzed by high valent oxo-rhenium(V) and (VII) complexes. The catalytic system PhSiH3/ReIO2(PPh3)2 (1 mol %) proved to be highly efficient for the reduction of a wide range of sulfoxides in excellent yields under mild conditions. This novel methodol. is also highly chemoselective, tolerating several functional groups such as -CHO, -CO2R, -Cl, -NO2, and double or triple bonds. The experimental process involved the reaction of 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole(cas: 73590-85-9).Formula: C17H19N3O2S
The Article related to chemoselective reduction sulfoxide silane rhenium catalyst, thio ether preparation, Benzene, Its Derivatives, and Condensed Benzenoid Compounds: Ethers, Sulfides, and The Corresponding Onium Compounds and other aspects.Formula: C17H19N3O2S
