2-Azaadamantane N-oxyl (AZADO)/Cu Catalysis Enables Chemoselective Aerobic Oxidation of Alcohols Containing Electron-Rich Divalent Sulfur Functionalities

The chemoselective oxidation of alcohols containing electron-rich sulfur functionalities (e.g., 1,3-dithianes and sulfides) into their corresponding carbonyl compounds with the sulfur groups can sometimes be a demanding task in modern organic chemistry. A reliable method for this transformation, which features azaadamantane-type nitroxyl radical/copper catalysis using ambient air as the terminal oxidant is reported. The superiority of the developed method was demonstrated by comparing it with various conventional alcohol oxidation methods.

Preparation of 3,3 the dimethyl generation of two propionic acid[...] -sulfur the new process

The invention belongs to the technical field of organic synthesis, and particularly relates to a new process for preparing 3,3'-dimethyl thiodipropionate. In the invention, methyl acrylate and an inorganic salt sodium hydrosulfide, taken as raw materials, are reacted in a proton solvent, so that the quantitative problem of reactants is solved, reaction raw materials are fully reacted, and the product yield is relatively increased; and a solution subjected to reaction can be applied for multiple times, and no three wastes are produced in the whole reaction process, so that the process is environmental-friendly, low in production cost and more conducive to industrial production.
