Abstract
Rhodium-catalyzed reactions of 3-ethynyl-2-pentamethyldisilanylthiophene derivatives (1a1c) have been reported. At 110 °C, compounds 1a1c reacted in the presence of a rhodium complex catalyst, yielding thiophene-fused siloles (2a2c) through intramolecular trans-bis-silylation. To understand [...] Read more.
Rhodium-catalyzed reactions of 3-ethynyl-2-pentamethyldisilanylthiophene derivatives (1a1c) have been reported. At 110 °C, compounds 1a1c reacted in the presence of a rhodium complex catalyst, yielding thiophene-fused siloles (2a2c) through intramolecular trans-bis-silylation. To understand the production of 2a from 1a, the mechanism was investigated using density functional theory (DFT) calculations. Full article
