1,2,3- versus 1,2-Indeno Ring Fusions Influence Structure Property and Chirality of Corannulene Bowls
Résumé
Annulated corannulenes 3−5 form via distinct synthetic pathways: (i) Pd-catalyzed sp 3 CH insertion, (ii) Pd-catalyzed aryl coupling, and (iii) silyl cation-promoted C−F activation/CH insertion. Crystal structure, redox, and photo-physical studies elucidate the differing influence of 1,2,3-versus 1,2-indeno ring fusions. Mono and dianions of 3−5 are characterized. Resolution of 4 gives enantiopure forms, allowing assessment of the bowl-inversion barrier.
