to each of the two allenic π-bonds, the less substituted of which reacts faster; the remaining two adducts arise by prior rearrangement of the allene to isoprene, which reacts mainly at the more substituted double bond to give 2,2,3,3-tetrafluoro-1-methyl-1-vinyl-cyclobutane (XI). Reaction of tetrafluoroethylene with tetramethylallene occurs only after rearrangement of the allene to 2,4-dimethylpenta-1
