Epoxidation of Alkenes (mCPBA)

R₂C=CR₂ + mCPBA → epoxide + mCBA

Visão geral

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.

Exemplo do cotidiano

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

Importância industrial

O óxido de etileno e o óxido de propileno, os epóxidos mais simples, são produzidos em mais de 20 e 10 milhões de toneladas por ano, respetivamente, e são fundamentais para a fabricação de poliésteres, poliuretanos e surfactantes.
