Epoxidation of Alkenes (mCPBA)

R2C=CR2 + mCPBA → epoxide + mCBA

개요

Meta-chloroperoxybenzoic acid (mCPBA) converts alkenes to epoxides (oxiranes) in a concerted syn-addition. The peracid oxygen inserts into the C=C bond, forming a strained three-membered ring. Epoxides are highly reactive due to ring strain and serve as versatile synthetic intermediates.

일상 속 예시

Epoxy resin adhesives (like Araldite) are made from epoxides that cross-link with hardeners to form incredibly strong bonds.
