Ethyl Difluoro(trimethylsilyl)acetate and Difluoro(trimethylsilyl)acetamides – Precursors of 3,3-Difluoroazetidinones
Autor: Jean-Paul Picard, Frédéric Frébault, Mallory Gobet, Michel Bordeau
Publikováno v: European Journal of Organic Chemistry. 2006:4147-4154
Difluoro(trimethylsilyl)acetamides 7 have been prepared from chlorodifluoroacetamides 5 by electrochemical silylation. When condensed with carbonyl compounds, they were shown to be precursors of 2,2-difluoro-3-hydroxyacetamides 8. N-(p-Methoxyphenyl)

Autor: Carole Moreau, Françoise Serein-Spirau, and Michel Bordeau, Claude Biran
Publikováno v: Organometallics. 20:1910-1917
A variety of functional aryl- and heteroarylchlorosilanes were prepared by electrochemical reduction of halothiophenes, halofurans, halopyridines, and substituted aryl halides in the presence of a large excess of commercial organodi- or trichlorosila
