AI Article Synopsis
- This study presents a method for creating complex organic compounds using rhodium-catalyzed reactions of sulfoximines and thiophenes, employing a chelation-assisted strategy.
- The process effectively produces compounds like [1]benzothieno[3,2-][1]benzothiophene (BTBT) and benzothiazine, demonstrating good compatibility with halogen substituents for further chemical transformations.
- The benzothiazine derivative generated exhibits a deep blue fluorescence with notable brightness, specific color coordinates, and a prolonged fluorescence lifetime.
Article Abstract
Reported herein is rhodium-catalysed oxidative C-H/C-H cross-coupling of -aryl sulfoximines with thiophenes a chelation-assisted strategy, which provides an efficient approach for the construction of [1]benzothieno[3,2-][1]benzothiophene (BTBT) and benzothiazine skeletons from easily available substrates. This protocol exhibits a good compatibility with halogen substituents, thus paving the way for further transformation to prepare various organic functional molecules. The resulting benzothiazine derivative shows a deep blue emission with Commission Internationale de 'Eclairage (CIE) coordinates of (0.15, 0.04), a high quantum yield, and a delayed fluorescence lifetime.
