설명

애플리케이션

Dibromomethane may be used for the cyclopropanation of alkenes via Simmons-Smith type reaction. It may also be used in a novel methodology for the preparation of reaction intermediates such as α-substituted acroleins, α-methylene esters, α-keto esters, α-methylene lactones, α-methylene lactams, and α-keto lactones.
