Published in 2019 at "ACS Omega"

DOI: 10.1021/acsomega.9b00315

Abstract: We have synthesized and theoretically calculated 5-methylisoindolo[2,1-a]quinoline derivatives as novel near-infrared absorption dyes via a ruthenium-catalyzed one-pot metathesis/oxidation/1,3-dipolar cycloaddition protocol. The reactivity in 1,3-dipolar cycloaddition was governed by the electronic effect of aromatic ring substituents.… read more here.
