Bingel reaction
WebThe reactions of C 60 and trichloromethyl anion (CCl 3 −) via both the Bingel mechanism and the carbene mechanism were comparably studied by means of density functional theory (DFT) computations.The Bingel mechanism is highly competitive as compared with the carbene mechanism that leads to the formation of C 60 (CCl 2).Unlike the carbene … WebIn the last two decades, well-optimized and widely used synthetic methods such as the Bingel cyclopropanation, 20 1,3-dipolar additions, 21, 22 and Diels–Alder reactions, 23, 24, 25, 26, 27, 28 provided readily accessible building blocks for higher molecular architectures and optoelectronic devices.
