various substituted thiophenes to synthesize poly-functionalized thiophenes in good to excellent yields. Apart from common functionalities compatible with iridium-catalyzed borylations, additional functional group tolerance to acyl (COMe), and trimethylsilyl (TMS) groups was also observed. High regioselectivities were observed in borylation of 3-and 2,5-di-substituted thiophenes. Electrophilic aromatic

thiophene-1,1-dioxides with strong EWGs has been described to date. Trifluoroperacetic acid in acetonitrile in the absence of water is shown to oxidise thiophenes, including examples possessing an electron-withdrawinggroup such as sulfonyl or alkoxycarbonyl. An easy and ready for scale-up procedure is developed, some formerly unknown thiophene-1,1-dioxides are obtained.
