Rhodium's (thanks for all the guidance) "The Peracid Oxidation of Isosafrole: A Review" document, under the Buffered Performic Acid Oxidation, DCM is used though most of the process. Toward the end, ethyl ether is used for an extraction. Would DCM work as well here, or is ethyl ether necessary? Also, is there a point in this procedure at which the bisulfite method could be used to isolate the MDP2P?
