- please explain the mechanism of ring opening of an epoxide by reaction with nucleophile under acidic conditionsLike other strong nucleophiles, triphenylphosphine attacks and opens epoxides. The initial product (a betaine) quickly cyclizes to an oxaphosphetane that collapses to an alkene and triphenylphosphine oxide. Show how this sequence might be used to convert cis-cyclooctene to trans-cyclooctene.What nucleophiles would form the following compounds as a result of reacting with 1-iodobutane?
