-CO). Novel uses of tungsten compounds are being investigated and the numerous emerging applications of tungsten compounds will further advance. Tungsten-dependent substances can take part in various functions of fuel cell systems such as electrolytes, catalysts, catalyst supports, and co-catalysts of numerous types of fuel cells. Tungsten is mostly obtained in four geological forms: skarn deposits, vein deposits, sheeted vein deposits, and pegmatites ( Wei et al. 2019 ). Reports revealed that organometallic compounds of various transition metals play a significant role in

Synthesis of Sulphones from Sulphonyl Fluorides and Organometallic Compounds Ahemd I. Khodair, A. A. Abdel-Wahab, and A. M. El-Khawaga Chemistry Department, Faculty of Science, Assiut University, Assiut, Egypt, A. R. E. Z. Naturforsch. 38b, 403-406 (1978); received January 19, 1978 Sulphones, Organometallic Compounds The reaction between sulphonyl fluorides and arylmagnesium bromides was investi- gated. The good yields of sulphones obtained demonstrates the potentialities of this reaction as a synthetic method for sulphones. Cadmium reagents were found to

Healy, and James Ruiz Chemistry Department, The University of Texas, Austin, Texas 78712 USA Abstract - A recent suggestion, that transition metal complexes of unsaturated ligands can be regarded as cruci- conjugated, is explored by studies of various complexes of Fe(II), the aromaticity of the resulting i systems being analyzed in terms of PMO theory. This approach is also applied to porphyrin

MA in the danpounds of type A, C, ard E, have been emitted.] B Reactive organometallic compounds from metallocenes 65 Metallocenes of the first row transition metals can be reduced by alkali metals in the presence, or with subsequent addition, of L to give either alkali rretal-free (B, D) or alkali metal-containing (C, E) transition metal calexes. Moreover, depending upon the transition metal, it is possible to remove selectively one or both of the C5H5-ligands fran the transition metal by choice of appropriate reaction conditions and stoichianetry.

In general, the bond energies D(M-X) for metals from the same group

eine didaktisch sehr geschickte Einführung in die Problematik der Adsorption anhand der Schilderung der Methoden und der damit an ausgewâhlten Systemen gewonnenen Information zu geben, wird dadurch jedoch nicht beeintrâchtigt. Das Werk erfüllt daher voli den im Vor- wort der Reihe „Chemische Taschenbücher" angesprochenen Zweck, gewisser- maBen eine Fibel darzustellen, und kann jedem Studenten warm empfohlen werden. Oerh.
