Organolead compounds
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. … Zobacz więcej Organolead compounds can be derived from Grignard reagents and lead chloride. For example, methylmagnesium chloride reacts with lead chloride to tetramethyllead, a water-clear liquid with boiling point 110 … Zobacz więcej Organolead compounds form a variety of reactive intermediates such as lead free radicals: Me3PbCl + Na (77 K) → Me3Pb and Zobacz więcej The C–Pb bond is weak and for this reason homolytic cleavage of organolead compounds to free radicals is easy. In its anti-knocking capacity, its purpose is that of a Zobacz więcej • Abadin, Henry G.; Pohl, Hana R. (2010). "5. Alkyllead Compounds and Their Environmental Toxicology".
