Carbonyl derivatives of boradiazaindacene via catalytic CO insertion.
Résumé
A methodological study is presented dealing with carbopalladation reactions on BODIPY dyes bearing aryl-halogen functions. Using this technique, several ester and amide groups were efficiently introduced on the dyes. These changes do not affect the optical properties of the dyes and thus allow the construction of new BODIPY-based functional dyes with carboxylic anchoring groups or peptide links.
