Bardin, V. V. published the artcileReactions of (triethylgermyl)pentafluorobenzene and perfluorotetraphenylgermane with nucleophiles, COA of Formula: C9H9F5Si, the publication is Zhurnal Obshchei Khimii (1990), 60(8), 1820-6, database is CAplus.
Oxygen- or nitrogen-containing nucleophiles attack the Ge atom in Et3GeC6F5, while sulfur-, carbon-, and hydrogen-containing nucleophiles attack the C-4 atom of the C6F5 group. (C6F5)4Ge undergoes Caryl-Ge bond cleavage in reactions with O– and S-nucleophiles, while reactions with C-nucleophiles give complex mixtures of products from cleavage and defluorination. Piperidine reacts with (C6F5)4Ge by substitution of an F atom, apparently due to steric screening of Ge.
Zhurnal Obshchei Khimii published new progress about 1206-46-8. 1206-46-8 belongs to catalysis-chemistry, auxiliary class Organic Silicones, name is Trimethyl(perfluorophenyl)silane, and the molecular formula is C9H9F5Si, COA of Formula: C9H9F5Si.
