文摘

Compounds with polarizable π systems that are susceptible to attack with nucleophiles at C–Hal (Hal = Cl, Br) bonds react with Pd(PPh₃)₄ to yield net oxidative addition. X-ray structures show that the resulting Pd(PPh₃)₂Hal groups greatly reduce intermolecular π–π interactions. The Pd-functionalized dyes generally exhibit solution-like absorption spectra in films, whereas their Hal analogues exhibit features attributable to aggregation.
