Iron(II) chloride-mediated addition of dialkylmagnesium to carbonyl compounds
Sada, Mutsumi,Matsubara, Seijiro
, p. 800 - 801 (2008)
Addition reactions to carbonyl compounds with a complex reagent, prepared from organomagnesium and iron(II) chloride, were examined. The reagent works as effective nucleophile to an easily enolizable ketone such as β-tetralone; it also added to keto ester chemoselectively. Copyright
Transition-metal chloride mediated addition reaction of diorganomagnesium to easily enolizable ketones
Sada, Mutsumi,Matsubara, Seijiro
scheme or table, p. 2612 - 2616 (2011/04/25)
An alkylation to an easily enolizable ketone, such as β-tetralone, is difficult to perform with Grignard reagent (RMgX) or with diorganomagnesium (R2Mg), because a deprotonation to form a magnesium enolate occurs predominantly. To avoid the prior enolization, a complex reagent of a transition-metal salt and R2Mg was examined: A combination of R 2Mg with iron(II) chloride (FeCl2) or ytterbium(III) chloride (YbCl3) gave a complex reagent that can realize a nucleophilic reaction to β-tetralone prior to the enolization. A combination of RMgX with these metal salts is inferior to a combination of R2Mg with them to obtain the nucleophilic complex reagent.
Acyclic monomers which when cured are reworkable through thermal decomposition

Compounds containing unsaturated aliphatic moieties which are linked to each other by a tertiary oxycarbonyl containing acyclic moiety are basis for compositions which are cured to polymer networks which are thermally decomposable to provide residue which can be dissolved to allow repair of inoperative assemblies by replacement of inoperative components or recovery or recycling of operative elements which are affixed in assemblies by the cured compositions.
