1H-1,2,3-Triazol-5-ylidenes: Readily Available Mesoionic Carbenes
Guisado-Barrios, Gregorio; Soleilhavoup, Michele; Bertrand, Guy American Chemical Society (2018)Classical carbenes are usually described as neutral compounds featuring a divalent carbon with only six electrons in their valence shell. It was only in 1988 that our group prepared the first isolable example, in which the ... -
