Abstract: Phenyl-substituted epoxides of the formula where R1 and R2 are each hydrogen, alkyl, alkenyl, phenyl, halogen, nitro, alkoxy, haloalkyl, phenoxy or phenylsulfonyl, are prepared by reducing a haloacetophenone to a halohydrin and reacting the halohydrin with an alkali metal hydroxide by a process in which the reduction with the alkali metal borohydride and the reaction are carried out in aqueous organic solution, or the cyclization of a halohydrin with an alkali metal hydroxide is carried out in an organic liquid.

Abstract: Prodn. of styrene oxides of formula (I) is effected by (a) reducing a haloacetophenone of formula (II) with an alkali(ne earth) metal or quat. ammonium borohydride, and (b) reacting the resulting halohydrin (III) with an alkali(ne earth) metal hydroxide. R1 and R2 = H, 1-4C alkyl, 2-4C alkenyl, phenyl, halogen, NO2, 1-4C alkoxy, 1-4C haloalkyl, phenoxy or phenylsulphonyl; X = halogen. Steps (a) and (b) are effected in a mixt. of H2O, a water-miscible organic solvent and opt. a water-immiscible organic solvent.
