The rates of chlorination of 4-acetamidophenyl benzoate, 1,3-bisbenzoyloxybenzene, and appropriate reference compounds by molecular chlorine in acetic acid at 25 deg C have been determined.By using the additivity principle, partial rate factors for chlorination directed by the benzoyloxy-group have thence been calculated, viz. fo-OCOPh 5.5, fm-OCOPh 0.059, fp-OCOPh 52.Comparison with analogous results obtained for the acetoxy-group allow estimates to be made of ?+ values for the benzyloxy-substituent.These values are used to discussed the course of halogenation of 2-benzoyloxynaphthalene.
