1 - Theory and mechanism
Epoxidation is a reaction of an alkene with a peroxycarboxylic acid (also called peracid) to produce an epoxide product, generally performed in inert solvents, such as dichloromethane. The epoxide product is a cyclic ether in which the ring contains three atoms. The alkene gains an oxygen from the peracid in a syn fashion. In this experiment, R-(－)-carvone is reacting with MCPBA, a peracid, to produce the epoxide product.
C10H14O + C7H5ClO3 --> C10H14O2 + C7H5ClO2
Since the rate of reaction depends on the electronic density of the double bond, and R-(－)-carvone has two double bonds, the reaction is regioselective. The more electron-riched …show more content…
