Abstract : The mechanism of the reaction of hexafluoroacetone with trimethylsilane has been reconsidered in the light of results now available on other reactions involving nucleophilic attack on hexafluoroacetone; these include the reaction of the ketone with alkyl halides in the presence of sodium and the reaction of hexafluoroacetone with tertiary amines. It is now thought probable that the initial reaction of a silane with hexafluoroacetone is a hydride abstraction, giving a fluorinated alkoxide ion. Claims that hexafluoroacetone forms complexes with compounds of group IV elements are reexamined, and it is concluded that present evidence does not support such a suggestion. (Author)
