WebThe carbons in an epoxide group are very reactive electrophiles, due in large part to the fact that substantial ring strain is relieved when the ring opens upon nucleophilic attack. Epoxides are very important intermediates in laboratory organic synthesis, and are also found as intermediate products in some biosynthetic pathways. WebAn electrophile is a reagent consisting of an atom, ion, or molecule that accepts electron pair to form a bond. It is an electron-deficient species that can be positively charged or neutral with vacant orbitals. An electrophile reacts with a nucleophile by accepting electrons through addition and substitution reactions.
