Organoleads carbon-hydrogen bonds

Because of the lower metal-carbon and metal-hydrogen bond strength, organolead hydrides are particularly unstable species and represent the least stable of those of the group 14 elements. Triorganolead hydrides are obtained at low temperatures by reduction of the halides with LiAlH4 (equation 45), but they decompose at 0 °C. 

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. 

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.
