“…One way of producing a volatile phase is by vaporizing a metal chelate. This type of compound, frequently employed in gas chromatography [41][42][43][44][45][46][47], usually has a low sublimation temperature and a high vapor pressure. It has been used to determine various metals, both with direct insertion of the gaseous sample into the flame [48][49][50][51][52][53][54][55][56][57] and by use of a graphite furnace [58].…”

Two synthetic routes to 14C‐labelled trimethyllead chloride ((CH3)3PbCl) from 14C‐methyl iodide (CH3I) were investigated. Alkylation of (CH3)3PbCl with labelled methylmagnesium halide, on a microscale, was less efficient for the synthesis of tetramethyllead ((CH3)4Pb) than was an electrochemical reduction of labelled CH3I at a sacrificial lead cathode. In the Grignard approach, unlabelled decyl bromide served as an initiator for the reaction of 14C‐CH3l with excess Mg and as a carrier during the subsequent alkylation of (CH3)3PbCl. In the electrochemical approach a two‐compartment cell, using dimethylformamide as solvent and sodium perchlorate as supporting electrolyte, offered several advantages over a single compartment reactor. The labelled (CH3)4Pb from both reactions was isolated by extraction, converted to (CH3)3PbCl by controlled oxidation with HCl and purified by thin layer chromatography.
