Research output: Contribution to journalArticlepeer-review


In the reaction of 1,4-bis(1-vinyl-2-pyrrolyl)benzene with hydrogen chloride and hydrogen bromide the hydrogen halide adds at the vinyl groups, and α-protonation takes place in both pyrrole rings. In reaction with the superacidic system HSO3F+SbF5 (in SO2ClF) position 5 of one heterocycle and position 4 of the other are protonated with retention of the vinyl groups.
