Oligomerisation of hexafluoro-1,3-butadiene (6) and hexafluorobut-2-yne (1) occur with tetrakis(dimethylamino)ethene (10), in the absence of a solvent. Hydrogen-terminated oligomers are obtained but in the presence of pentafluoropyridine (12) or tetrafluoropyrimidine (17), simple trapping products are obtained. It is concluded that the polymerisation of 6 occurs by very rapid rearrangement to 1, followed by polymerisation of the latter.
