Abstract
It has been shown that a number of nucleophilic and weakly electrophilic reagents (organolithium and organomagnesium compounds, metallic lithium, potassium permanganate, sodium ethoxide, diaryl disulphides, sulphur, ozone, hypochlorous acid and iodine/iodide) selectively cleave the lead---lead bond of hexaphenyldilead. No lead---phenyl bond cleavage occurs with these reagents. The reactions with lithium,
