I cant do it myself but please someone remove those silly red arrows in the Nicolau synthesis..... they are wrong and not professional at all. Thanks — Preceding unsigned comment added by Devvochem ( talk • contribs) 08:14, 27 July 2011 (UTC)
Please correct the falsely (re)introduced statement by Christian75, "without formation of significant amounts of dimethylsulfide as a side product". It is without question that, as outlined in the mechanism, dimethylsulfide is generated. Maybe the confusion stems from reference [2], in which it is stated: "A by-product, the methyl thiomethyl ether derivative of alcohol, which often arises significantly in the oxidation with acetic anhydride-DMSO, is negligible." This refers to a (undesired) by-product of the alcohol oxidation, which is also explained at the end of the Organic Chemistry Portal: Swern Oxidation article: "If the temperature is not kept near -78°C, mixed thioacetals may result". It is these mixed thioacetals ("methyl thiomethylethers") that Parikh and Doering refer to in [2], not dimethylsulfide. — Preceding unsigned comment added by 131.111.120.42 ( talk) 11:21, 26 June 2019 (UTC)
