Extraction of Acetals of Phenyl-Propargyl Aldehyde Using the Metod of Liquid Column Chromotography

Abstract

The interreaction of substrates containing cyclopropane fragment with initial allyl and butyl alcohol, the influence of bromide atom in a gem-dichlorocyclopropane ring on the direction of the reaction with alcohol. The reaction of O-alkyllation 2-bromide-2-phenyl-gem-dichlorocyclopropane with alcohol in dimethylformamide with solid sodium hydroxide and without a phase transfer catalyst occurs selectively and produces the corresponding acetals of phenyl-propargyl aldehyde. The optimal conditions were selected for the reaction. It was researched and established that gem-dichlorocyclopropanes with a bromide atom in the cycle can also participate in such transformations. Acetals of phenyl-propargyl aldehyde were extracted from the reaction mix using the method of liquid column chromotography
