The preparation of alkyl or aryl radicals, primarily methyl radical by thermal decomposition of organolead compounds under a vacuum system is generally referred to as the Paneth technique. The tetramethyl lead is decomposed at 1–2 mmHg of pressure in a glass tube heated either by a mobile Bensen burner or by an electric furnace. The study finds that tetraethyl lead reacts in the same fashion, whereas other higher order alkyl lead compounds give a mixture of radicals upon thermal decomposition. Besides lead, other metals have also been found to react with methyl radicals. This technique provides a convenient method for the production of radicals.
