## 2-Nitro-2-phenylthio oniranes (3), prepared by nucleophilic epoxidation of I-nitro-I-phenyllhio alkenes (I), react with a v&y of heteroatomic nucleophiles to give a-substituted S-phenylthio esters (2). Of special note is the efficient reaction of 2-n&o-2-phenylthio oxiranes with boron trifruOride
