, (2020/06/29)
While aryl germanes have recently found usage as coupling partners in powerful catalytic applications, the synthetic access to this promising functionality is currently limited. This report details the straightforward synthesis of functionalized aryl trie
?-Silicon-effect-promoted intermolecular site-selective C(sp3)-H amination with dirhodium nitrenes

A dirhodium-catalyzed, ?-selective C-H amination of organosilicon compounds has been developed. Primary C(sp3)-H bonds of silylethyl groups and secondary C(sp3)-H bonds of silacycloalkanes can be selectively converted to C-N bonds at the ?-position of the silicon atoms. The experimental data and theoretical calculations indicate that the strong s-donor ability of the carbon-silicon bonds is responsible for the ?-selectivity. Kinetic isotope effects clearly demonstrate that the C-H bond cleavage step is not turnover-limiting, but selectivity-determining.
General access to para-substituted styrenes

, p. 113 - 119 (2007/10/03)
A simple and efficient procedure has been developed for the synthesis of organogermanium compounds and styrenes para-substituted with groups containing an atom of the 14th group by one-pot reaction of halogenosilanes, germanes or stannanes, organic halides and magnesium using ultrasound methods.

Reactivities of triethylgermylborate in methanol
Nanjo, Masato,Matsudo, Kazuhiko,Mochida, Kunio
, p. 1086 - 1087 (2007/10/03)
The reactivity of lithium (triethylgermyl)triphenylborate, prepared from unsolvated triethylgermyllithium and triphenylborane, with organic substrates in methanol was investigated. The germylborates reacted with organic halides and acyl halides to give th
Photochemical Reactions of Aryltriethylgermanes and Diethyldiphenylgermane
Kobayashi, Michio,Kobayashi, Masanori
, p. 2807 - 2810 (2007/10/02)
Aryltriethylgermanes and diethyldiphenylgermane were found to split easily to generate germyl radicals by irradiation with a medium-pressure mercury lamp in hexane or cyclohexane.The germyl free radicals produced reacted with hydrocarbon radicals generated from the solvent by hydrogen abstraction either by recombination or by disproportionation.
ASSISTANCE NUCLEOPHILE DANS DES REACTIONS DE REDUCTION D'ORGANOHALOGENO- ET HALOGENO-GERMANES PAR DES REDUCTEURS DOUX R3M(IVB)-H ET RCHO: GERMYLANIONS, DERIVES FONCTIONNELS DU GERMANIUM
Castel, A.,Riviere, P.,Satge, J.
, p. 137 - 146 (2007/10/02)
Catalytic activity of nuclophiles such as tertiary amines and diazo derivatives in the reduction of halogermanes by means of gentle reductive agents, such as R3M(IVB)-H or RCHO, has been shown.In the particular case of enolisable aldehyde, a competition between nucleophilic substitution at the metal and germanium-halogen bond reduction has been observed.Transposition of enoxygermanes formed through the substitution process, leads to β-germylaldehydes.
