Chapter 9 The detection of inorganic and organometallic compounds by electron-capture gas chromatography

Abstract: Publisher Summary This chapter discusses the detection of inorganic and organometallic compounds by electron-capture gas chromatography. The chapter describes the determination of metals as their chelate derivatives, the determination of organoarsenic compounds, the determination of organomercury compounds, the determination of selenium as piazselenols, the determination of inorganic anions, and the determination of miscellaneous inorganic compounds. The application of the electron-capture detector to the analysis of inorganic and organometallic compounds is limited primarily by the poor chromatographic properties of many of these substances. Most metals and their salts are either ionic or too involatile to be separated by gas chromatography. A further problem is the high chemical reactivity of many organometallic compounds which results in their loss at low levels due to irreversible interactions with the chromatographic system. However, when these problems can be overcome, excellent sensitivity can be obtained with the electron-capture detector for appropriately substituted inorganic compounds.

Study of the mechanism of the alkylation reaction of organomercury compounds by triarylmethane derivatives

Abstract: 1. The reaction of ethyl esters ofα-bromomercuryarylacetic acids proceeds at the carbon atom in dichloroethane and at the oxygen atom in nitromethane. 2. The reaction of mercurated esters with Ar3CBr is accomplished through the preliminary formation of a complex between the reagents and is first order with respect to the complex. The reaction of mercurated esters with Ar3CBr · HgBr2 proceeds according to a bimolecular mechanism. 3. The reactions of arylmercury bromides with tetraphenylbromomethane and its complex with mercuric bromide proceed according to a single mechanism. The reaction with trityl bromide is accelerated by additions of iodide ions.

Oxidation of 3- and 4-carenes with mercuric acetate in acetic acid

Abstract: 1. A study was made of the oxidation of 3-carene with Hg(OAc)2 in acetic acid at 23 and 86°, and with (HgOAc)2 at 90°. The action of both of the oxidizing agents leads to the same acetylative oxidation products: the acetates of p-mentha-1,5-dien-8-ol and p-mentha-1(7),5-dien-8-ol. 2. The products of the oxidation of 4-carene with Hg(OAc)2 in acetic acid at 20° contain the acetates of p-mentha-1,5-dien-8-ol and p-mentha-1(7),5-dien-8-ol. 3. The formation of organomercury compounds of composition C18H26O8Hg3 occurs when the 3- and 4-carenes are oxidized with Hg(OAc)2 at room temperature.
