Figure 2: Scope and structure of perfluoro-π-extended pentalene derivatives.
From: Intramolecular C–F and C–H bond cleavage promoted by butadienyl heavy Grignard reagents
(a) Scope of C–F bond activation via heavy Grignard reagents. (b) Thermal ellipsoid plot of perfluorodibenzopentalene 2e with 50% thermal ellipsoids. Hydrogen atoms are omitted for clarity. (c) Thermal ellipsoid plot of perfluorodinaphthopentalene 2g with 50% thermal ellipsoids. Hydrogen atoms are omitted for clarity. The whole molecule of 2g was disordered. The major part was shown above.
