Probing hyperconjugative aromaticity in 2H-pyrrolium and cyclopentadiene containing Group 9 transition metal substituent: Bridged carbonyl ligands can enhance aromaticitySubmitted by Jun Zhu on Sun, 01/10/2021 - 10:34
Aromaticity and hyperconjugation are two fundamental concepts in organic chemistry. By combination of the two concepts together, the resulting hyperconjugative aromaticity has attracted considerable attention from both theoretical and computational chemists. However, previous studies are mainly focused on the main group chemistry. For the hyperconjugative aromaticity in the transition metal chemistry, the studies are limited to groups 10 and 11.
