Room-temperature chemical synthesis of c2
WebHere, we present the chemical synthesis of C2 from a hypervalent alkynyl-λ3-iodane in a flask at room temperature or below, providing experimental evidence to support theoretical predictions that C2 has a singlet biradical character with a quadruple bond, thus settling a long-standing controversy between experimental and theoretical chemists ... Given that C2 generated at room temperature or below behaves exclusively as a singlet biradical, as theoretically predicted for the ground state, we examined whether this ground-state C2 would serve as a molecular element for the formation of various carbon allotropes. Today, nanocarbons such as graphene, CNTs, … See more The key strategy underlying the present achievement is the use of hypervalent iodane chemistry15,16,17, aiming to utilize the phenyl-λ3-iodanyl moiety as a … See more Taking account of the fact that quantum chemical calculations suggest a relatively stable singlet biradical C2 with quadruple bonding in the ground state, we next … See more
