The orientation in the ring opening reactions of epichlorohydrin and epibromohydrin with phosphorus oxychloride and phosphorus oxybromide has been studied. The IR and NMR spectra of the reaction products were compared with those of the authentic phosphates.<BR>It was found that the “normal” opening of the oxirane ring occurred exclusively or predominantly, at least, in all cases studied. Thus, <I>tris</I>- (1, 3-dihalo-2-propyl) phosphates were obtained in a good yield. Major factors affecting the direction of ring opening are discussed.
