Bowl-Shaped Fragments of C sub(70) or Higher Fullerenes: Synthesis, Structural Analysis, and Inversion Dynamics

Super bowl: Fragments of C sub(70) or higher fullerenes were easily prepared from 1,8-bis(arylethynyl)naphthalenes. The curved structures were identified by X-ray crystallography. These rigid bowl-shaped molecules have a deep bowl depth (approximately 2.30Aa) and their bowl inversions proceed via an...

Zusammenfassung:Super bowl: Fragments of C sub(70) or higher fullerenes were easily prepared from 1,8-bis(arylethynyl)naphthalenes. The curved structures were identified by X-ray crystallography. These rigid bowl-shaped molecules have a deep bowl depth (approximately 2.30Aa) and their bowl inversions proceed via an S-shaped transition structure with a very high inversion barrier (approximately 80kcalmol super(-1)).
