FoLLowing the first synthesis of an organoLead compound by Loewig in 1852, progress sLowed markedLy in organoLead chemistry. Then, the discovery of the outstanding performance of organoLead compounds as antiknock additives to automobiLe gasoline turned organoLead chemistry into one of the main areas of organometallic chemistry. Large-scaLe industriaL procedures for synthesizing tetraethyLLead and other tetraaLkyLLead compounds and entireLy new techniques, such as handling Large amounts of sodium-Lead aLLoys or eLectroLyzing Grignard soLutions, were deveLoped, and many other industriaL projects as weLL as toxicoLogicaL and environmentaL studies brought a tremendous increase of knowLedge. Therefore, a compiLation of the avaiLabLe data in organoLead chemistry seemed justified. In the present series onLy compounds containing at Least one Lead-to-carbon bond are considered

Lead (Pb) presents an active nuclei (207Pb) with spin quantum number 1/2. In liquid state NMR it has been used to study organo-lead compounds, whereas in ...

Organolead Compound - an overview | … Surprisingly, organolead compounds have found little application in organic synthesis. However, in a number of circumstances they can perform effectively. Tetraalkyllead compounds such as Et 4 Pb and Bu 4 Pb are stable, storable and selective alkylating agents towards aldehydes in the presence of Lewis acids such as TiCl 4 (Equation (25)).Transfer of an ethyl group occurs rapidly and in
