Chemical Research Letters, April 2021. With the volume and accessibility of scientific research increasing across the world, it has never been more important to continue building the reputation we’ve spent the past two centuries establishing. 93-97-0, Name is Benzoic anhydride, molecular formula is C14H10O3, COA of Formula: https://www.ambeed.com/products/93-97-0.html, belongs to isothiazole compound, is a common compound. In a patnet, author is Zhou, Kaida, once mentioned the new application about 93-97-0.
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.
Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. Keep reading other articles of 93-97-0.
