Meso enamine substituted BODIPYs

Abstract

Different enamines were introduced at the meso position of the BODIPY by catalyst free oxidation of tert-amines and in situ cross coupling with 8-chloro BODIPY. The reaction conditions were optimized to achieve better yields. The reaction works well with aliphatic tert-amines bearing an N-(CH–CH–) backbone. The N-alkyl substituents perturb the optical properties of enamine substituted BODIPYs. © 2014 The Royal Society of Chemistry.
