New Advances in Chemical Research in 2021. SDS of cas: 93-97-0, You could be based in a university, combining chemical research with teaching; in a pharmaceutical company, working on developing and trialing new drugs; helping to ensure national healthcare provision keeps pace with new discoveries. 93-97-0, Name is Benzoic anhydride, SMILES is O=C(OC(C1=CC=CC=C1)=O)C2=CC=CC=C2, belongs to isothiazole compound. In a article, author is Zhou, Kaida, introduce new discover of the category.
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, SDS of cas: 93-97-0.
