Pyrrole (2; 50 mmol) and heptafluorobutyraldehyde (7; R=CF3CF2, as the hydrate, 25 mmol ) were condensed in tetrahydrofuran in the presence of acid catalyst as described above to give bis-(pyrrol-2-yl) hepta-fluoroprop-1-ylmethane (8; R=CF3CF2) in >50% isolated yield. GCMS m/z; 314 (M+, 22%), 145 (100%); 1H NMR (δ, CDCl3 at 7.24); 4.92 (t, 1H), 6.22 (d, 4H), 6.75 (s, 2H), 8.07 (bs, 2H).
