Novel Perylene Derivatives as Highly Photostable Fluorescent Dyes [PDF]

CHIMIA, 1994
Perylene-3,4-dicarboxylic imides are prepared by a new decarboxylizing condensation with moderately sterically hindered primary amines. Perylene-3,4-dicarboxylic anhydride is prepared via a saponification reaction of the dicarboximide and is a ...

Visible-light-driven reductive coupling of aromatic ketones using perylene derivatives as photoredox catalysts: Improvement of reaction efficiency by the addition of acetic acid

Results in Chemistry, 2021
The photoredox-catalyzed reductive coupling of aromatic ketones using perylene as a simple organic photoredox catalyst was improved significantly by the addition of acetic acid. For example, the reductive coupling of acetophenone in the absence of acetic
