Abstract
La presente invención se refiere a un proceso para la síntesis de una cis-olefina a partir de un alcohol cis-olefínico, caracterizado porque comprende: a) hacer reaccionar un alcohol cis-olefínico con una fuente de un ión de metal alcalino el cual es un ión litio y/o sodio para formar un primer producto de reacción; b) luego poner en contacto el primer producto de reacción así formado con un compuesto de haluro de sulfonilo en donde el compuesto de haluro de sulfonilo es un haluro de alquil o aril sulfonilo en donde el haluro es cloruro o bromuro para formar un segundo producto de reacción, c) luego poner en contacto el segundo producto de reacción así formado con una sal cuprosa y un haluro de dialquilmagnesio o alquilmagnesio en donde el haluro es ioduro, bromuro, o cloruro para formar un tercer producto de reacción que comprende una cis-olefina, los pasos son llevados a cabo en un solvente orgánico adecuado.The present invention relates to a process for the synthesis of a cis-olefin from a cis-olefinic alcohol, characterized in that it comprises: a) reacting a cis-olefinic alcohol with a source of an alkali metal ion which is a lithium and / or sodium ion to form a first reaction product; b) then contacting the first reaction product thus formed with a sulfonyl halide compound where the sulfonyl halide compound is an alkyl or aryl sulfonyl halide where the halide is chloride or bromide to form a second product of reaction, c) then contacting the second reaction product thus formed with a cuprous salt and a dialkylmagnesium or alkylmagnesium halide where the halide is iodide, bromide, or chloride to form a third reaction product comprising a cis-olefin , the steps are carried out in a suitable organic solvent.
