1 synthesized from reaction of this nucleophile with ($0-dichlorobenzene)(~ 5- cyclapentadienyl) iron hexafluorophosphate. 12 Nucleophile 1 was chosen because it reacts with bromobenzene 2 in liquid ammonia under photostimulation in a molar ratio 1: 2 to give a 30% yield of substitution products. This percentage based on the bromobenzene used corresponds to the formation of mono-and disubstitution products, 3 and 4, ...
