The fluoride ion-catalysed rearrangement of 3,6-difluoro-4,5-bisheptafluoroisopropylpyridazine
Abstract
The rearrangement of the 4,5- to 4,6-bisheptafluoroisopropylpyridazine (3)→(4) in the presence of fluoride ion is reported, and the importance of this reaction in the formation of the trisheptafluoroisopropyl derivative (5) is indicated.
