Brief description of the isomerisation of double bonds isolated of double bonds conjugated in of the cyclodextrins - octadienes optionally substituted

摘要

The invention relates to a method for the isomerization of double bonds isolated of double bonds conjugated in of the cyclodextrins - octadienes optionally substituted, with the aid of an amide of alkali metal or alkaline-earth - metal, optionally in the presence of a solvent. / p & & p & the method consists in to prepare the amide of alkali metal or alkaline-earth - metal in the absence of the missing and in the atmosphere of inert gas, in the presence of the cyclodextrins - octadiene has isomerize, and a lead to temperatures of 70 a, 200c. / p & & p & the method makes it possible to reduce the quantity of catalyst and even to eliminate the solvent.
