- HALIDE REDUCTION DIHYDROCARBYLMAGNESIUM MIXTURES
-
This invention provides a process for reducing the amount of soluble halide in a solution comprising a liquid organic medium, at least one viscosity reducing agent, at least one dihydrocarbylmagnesium compound, and an initial amount of soluble halide. The process comprises mixing at least one alkali metal with the solution at a mole ratio of alkali metal to magnesium of less than about 1:2.5, thereby forming precipitated soluble halides. Also provided by this invention is a process for reducing the amount of soluble halide in a slurry comprising a liquid organic medium, at least one viscosity reducing agent, at least one dihydrocarbylmagnesium compound, solids from the formation of said dihydrocarbylmagnesium compound, and an initial amount of soluble halide. This process comprises mixing at least one alkali metal with the slurry at a mole ratio of alkali metal to magnesium of less than about 1:1.25, thereby forming precipitated soluble halides.

- Process for making α,β-unsaturated carboxylic acids
-
α, β-Unsaturated acids of the formula STR1 wherein R1 signifies C1 -C5 -alkyl and Ar signifies an aryl group which is optionally substituted by one or more substituents selected from the group consisting of halogen, phenyl, C1 -C5 -alkyl, C1 -C5 -alkoxy, perfluorinated C1 -C5 -alkyl or perfluorinated C1 -C5 -alkoxy can be obtained from new or known compounds of the formula STR2 Compounds I can be converted by asymmetric hydrogenation into corresponding optically active saturated acids.

- Stepwise organomagnesium synthesis of mixtures of ethyletoxysilanes and ethylchlorosilanes
-
Mixture of ethylethoxy- and ethylchlorosilanes was prepared in a toluene solution by successive reaction of magnesium with a mixture of ethyl chloride and tetraethoxysilane and then with a mixture of ethyl chloride and tetrachlorosilane.
