“…For this purpose, we identified the two Heck coupling partners to start our investigation and optimize our target reaction with a) a properly functionalized carborane bearing a styrene moiety ( o ‐Me‐CB , o ‐Ph‐CB , m ‐Me‐Cb and m ‐Ph‐Cb ) and b) the highly fluorescent BODIPY dye 1 (Scheme ), which exhibits an absorption maximum at λ abs =502 nm. The 1,3,5,7‐tetramethyl BODIPY derivative 1 has been synthesized by an acid‐catalyzed condensation of 2,4‐dimethylpyrrole with p ‐bromobenzaldehyde, and the styrenyl‐containing carborane derivatives have been successfully synthesized by lithiation of the parent closo ‐carborane cluster followed by the addition of 4‐vinylbenzyl chloride, as described in the literature ,…”
