Organolead compounds are chemical compounds containing a chemical bond between carbon and lead. Organolead chemistry is the corresponding science. The first organolead compound was hexaethyldilead (Pb2(C2H5)6), first synthesized in 1858. Sharing the same group with carbon, lead is tetravalent. Going down the carbon group the C–X (X = C, Si, Ge, Sn, Pb) bond becomes weaker and the bo…
