Abstract
In this report the successful generation of the non‐isolated pentagon rule (non‐IPR) fullerene fragment via regioselective cyclodehydrofluorination of a specially designed precursor under laser ionization condition is presented. It is demonstrated that the transformation of the precursor molecule to the highly strained non‐IPR bowl‐shaped hydrocarbon can be achieved effectively at rather low laser fluences, despite the presence of fused pentagons in the structure. This finding opens up a venue towards the rational synthesis of individual isomers of non‐IPR fullerenes and other related non‐IPR architectures by the bottom‐up strategy. The retrosynthetic analysis of fluoroarene‐based precursor molecules for non‐IPR fullerenes C36–C50 is discussed.
