Carbonyl Derivatives of Boradiazaindacene via Catalytic CO Insertion

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.
