New discoveries in chemical research and development in 2021, Chemistry involves the study of all things chemical – chemical processes, how they change and how they react in certain situations. 93-17-4, Name is 3,4-Dimethoxyphenylacetonitrile, SMILES is C1=C(CC#N)C=CC(=C1OC)OC, in an article , author is Zhou, Kaida, once mentioned of 93-17-4, COA of Formula: https://www.ambeed.com/products/93-17-4.html.
An efficient route to diverse 3-sulfonated-2,3-dihydrobenzo[d] isothiazole 1,1-dioxides is achieved through a three-component reaction of 2-ethynylbenzenesulfonamides, DABCO-bis(sulfur dioxide), and aryldiazonium tetrafluoroborates. The corresponding sulfonated benzosultams are produced in moderate to good yields. During the reaction process, the in situ generated arylsulfonyl radical via addition of an aryl radical to sulfur dioxide and the subsequent single electron transfer would be the key steps for the final outcome. DABCO acts as the carrier for single electron transfer, as well as a base to promote the C-N bond formation.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 93-17-4. COA of Formula: https://www.ambeed.com/products/93-17-4.html.
