TCI B6766 Benzo[b]thiophene 1,1-Dioxide is the fully oxidised sulfone derivative of benzothiophene, in which the strongly electron-withdrawing sulfonyl group renders the five-membered ring markedly electron-poor. This reactivity profile makes it a valuable dienophile in Diels-Alder cycloadditions and an acceptor in conjugate addition chemistry. Cycloadducts derived from it can often extrude sulfur dioxide, providing an elegant route to fused polycyclic aromatic frameworks. AMI Scientific supplies this TCI compound in two research-scale sizes; store it cool, dry, and protected from light in a tightly closed container.
