“…The latter decreases, to some extent, the narcotic action of thiopental sodium, barbital sodium and chloral hydratst, while 2-thienyl-silatrane, on the contrary, considerably increases the duration of anaesthesia induced by thiopental sodium (Table 32). 62 Analysis of the data accumulated up to the present demonstrates that:…”

The literature data and the results of our own investigations on the comparative study of the biological activity of isostructural organogermanium and organosilicon compounds have been summarized. It has been shown that the series of organogermanium and organosilicon compounds is more active than the carbon analogues, the majority of organogermanium compounds are less toxic than the sila analogues, the biological activity of the compounds under study appears to be similar but can dramatically differ in the degree of activity, and, moreover, in some particular cases sila and germa analogues exhibit the opposite biological effects.

Lithium atoms were cocondensed with eight aromatic five‐membered heterocycles in the presence of THF at 77 K. In the case of the oxygen‐ and sulfur‐containing heterocycles (furans and thiophenes), the reaction resulted in C−H bond activation and led to the corresponding aryllithium compound. The other heterocycles (pyrroles) failed to react with lithium atoms in the presence of THF. A special case was found when oxazole was reacted under these cocondensation conditions; here a dilithiated product was obtained. DFT (B3LYP/6‐31G**) calculations were carried out in order to interpret the pathways of the reactions and the possible intermediates. For all the reactions π‐ and σ‐complexes between lithium clusters and the heterocycles were found as stable intermediates. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
