Abstract
A Grignard-type process for the preparation of unsaturated organic compounds. The process comprises contacting an unsaturated organic halide with magnesium metal in a mixture of ether and a polar halogenated hydrocarbon co-solvent, filtering the reaction product from the reaction step and thereafter, treating the reaction product filtrate from the filtration step to obtain the desired unsaturated organic compounds.
Claims6
A method for the preparation of unsaturated organic compounds, the method comprising:
- (I) contacting an unsaturated organic halide with magnesium metal in a mixture of ether and a polar halogenated hydrocarbon co-solvent or a mixture of ether and a mixture of polar halogenated hydrocarbon co solvents;
- (II) filtering the reaction product from step (I);
- (III) treating the reaction product filtrate from step (II) to obtain the desired unsaturated organic compounds.
A method for the preparation of unsaturated organic compounds, the method comprising:
- (A) contacting an unsaturated organic halide with magnesium metal in a mixture of ether and a polar halogenated hydrocarbon co-solvent or a mixture of ether and a mixture of polar halogenated hydrocarbon co-solvents wherein:
- (i) the temperature is in the range from 5° C. to 200° C., and
- (ii) the pressure is in the range from ambient pressure to about 200 psig.
