Stereoselective cyclomagnesiation of 1,6-heptadienes catalyzed by zirconocenes: Effects of substituents, solvent and magnesium reagents
摘要:
Zirconocene dichloride acts as a catalyst precursor for the stereoselective cyclomagnesiation of an array of substituted 1,6-heptadienes in the presence of butylmagnesium chloride to form trans 1,2-(bis)methylmagnesium substituted carbocycles.
