Linear Amine-Linked Oligo-BODIPYs: Convergent Access via Buchwald-Hartwig Coupling

Working Paper
This content is a preprint and has not undergone peer review at the time of posting.

Abstract

A convergent route towards nitrogen-bridged BODIPY oligomers has been developed. The synthetic key step is a Buchwald-Hartwig cross-coupling reaction of an alpha-amino-BODIPY and the respective halide. Not only does the selective synthesis provide control of the oligomer size, but the facile preparative procedure also enables easy access to this type of dyes. Furthermore, functionalized examples were accessible via brominated derivatives.
