Synthese von Sulfolenobilinen und deren Cyclisierung zu Chlorinatozink-Fulleren-Dyaden
摘要:
A novel chlorinatozinc-fullerene dyad 18 was synthesized to model the photosynthetic reaction center. The synthetic key step for the formation of the dyad 18 is an unusual one-pot reaction of the (sulfolenobilinato) nickel rac-16a,b with concomitant generation of the chlorin macrocycle and linkage to the [5,6]fullerene-C-60-I-h. This one-pot reaction is a complex cascade of single reaction steps with a total yield of 32% and an average yield of 83% for the individual steps. The chlorinatozinc-fullerene dyad is so far one of three examples that contain chlorin moieties, the chromophores in naturally occurring photosynthetic systems.
