Reaction of Cyclohexa-1,2,3-triene with N,α-Diphenylnitrone: Formation of Seven-Membered Cyclic Amines via Piradone Derivatives. -Treatment of the triflate (I) with CsF generates cyclohexa-1,2,3-triene, the smallest cyclic allene known to undergo fast dimerization. However, it can be trapped by dia
