New Advances in Chemical Research in 2021. Chemistry is a science major with cience and engineering. The main research directions are chemical synthesis,and research on the structure and performance of functional materials. 93-97-0, Name is Benzoic anhydride, molecular formula is C14H10O3, belongs to isothiazole compound. In a document, author is Zhou, Kaida, introduce the new discover, Name: Benzoic anhydride.
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.
Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield. If you are hungry for even more, make sure to check my other article about 93-97-0, Name: Benzoic anhydride.
