Abstract RU 2440966 C1

FIELD: chemistry.

SUBSTANCE: present invention relates to a method of producing methylene-hem-diaryloxycyclopropanes, which are used as corrosion inhibitors, as well as reagents in organic synthesis. The method involves O-alkylation of corresponding substituted phenols with chloromethyl-hem-dichlorocyclopropanes in dimethyl sulphoxide in microwave radiation conditions in the presence of an interphase catalyst Catamin AB and aqueous sodium hydroxide solution for 40 minutes.

EFFECT: method enables to obtain desired products with high output and prevents formation of by-products.
