Organoleads carbon-lead bonds

The usual method for the preparation of organolead halides is by the action of hydrogen halides upon tetra-organoleads. Initial reaction involves fission of one carbon-lead bond, with loss of a further alkyl/aryl group under more vigorous conditions. 

Organolead compounds comprise the broad class of structures that are characterized by at least one carbon atom bonded directly to a lead atom. 

Organolead compounds contain a direct chemical bond between carbon and lead. Their use is rather limited, partially due to their toxicities, although their toxicides are not too high. 

Some special procedures which are not discussed are mentioned in Table III. Also of interest are those reactions of functionally substituted organolead compounds, in which the functional groups are exchanged without cleavage of the lead-carbon bond (see Table III). 

Organolead compounds contains at least one covalent bond between lead and carbon. The organolead compoimds that will be dealt with in this review include ... 

Finally, lead chemical compounds can be classified as organic (i.e. containing carbon and hydrogen) or inorganic. Organic lead compounds comprising one or more lead-carbon bond are described as organolead compounds. Examples of these include tetraethyl lead and tetramethyl lead, both of which have been extensively used as anti-knock additives in petrol.
