Chotana, Ghayoor A. published the artcileIridium-catalyzed borylation of thiophenes: versatile, synthetic elaboration founded on selective C-H functionalization, Category: chlorides-buliding-blocks, the publication is Tetrahedron (2008), 64(26), 6103-6114, database is CAplus and MEDLINE.
Iridium-catalyzed borylation has been applied to various substituted thiophenes to synthesize poly-functionalized thiophenes in good to excellent yields. Apart from common functionalities compatible with iridium-catalyzed borylations, addnl. 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 C-H/C-Si bromination on thiophene boronate esters is shown to take place without breaking the C-B bond, and one-pot C-H borylation/Suzuki-Miyaura cross-coupling has been accomplished on 2- and 3-borylated thiophenes.
