The epoxidation of valencene by m-CPBA has been investigated within the DFT at the B3LYP/6-311(d,p) computational level. The chemo- and stereoisomeric reaction paths involving the two C=C double bonds of valencene have been analyzed. DFT computations account for the high chemospecifity involving the endo-double bond and the high stereospecifity, in total agreement with the experimental outcome. An ELF examination of epoxidation shows that the establishment of the two new single C-O bonds is a little asynchronous.
