Enhanced N-directed Electrophilic C-H Borylation Generates BN-[5]- and [6]-helicenes with {Improved|Enhanced} Photophysical Properties
Helicenes are chiral polycyclic aromatic hydrocarbons (PAHs) of {significant|substantial|considerable|important} interest e.g. in supramolecular chemistry, {materials|supplies|components} science and asymmetric catalysis. Herein an enhanced N-directed electrophilic C-H borylation methodology has been {developed|created}…
