INVESTIGATIONS ON ORGANOLEAD COMPOUNDS .V. LEAD-LEAD BOND CLEAVAGE REACTIONS OF HEXAPHENYLDI-LEAD

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 leadlead bond of hexaphenyldilead. No leadphenyl bond cleavage occurs with these reagents. The reactions with lithium, potassium permanganate, diaryl disulphides, ozone, hypochlorous acid and iodine/iodide form useful synthetic procedures for the preparation of triphenyl-lead derivatives from the readily available hexaphenyldilead. © 1968.
