[hydroxy(tosyloxy)iodo]arenes bearing 2-thienyl, 3-thienyl, N-tosyl-4-pyrazolyl, 3-trifluoromethylphenyl, and 3,5-bis(trifluoromethy)phenyl as an aromatic group, and [hydroxy(phosphoryloxy)iodo]arenes bearing N-tosyl-4-pyrazolyl, 3-trifluoromethylphenyl, and 3,5-bis(trifluoromethy)phenyl as an aromatic group, were prepared. alpha-Tosyloxylation and alpha-phosphoryloxylation of ketones with these compounds were
具有2-噻吩基,3-噻吩基,N-甲苯磺酰基-4-吡唑基,3-三氟甲基苯基和3,5-双(三氟甲基)苯基作为芳族基团和[羟基(磷酰氧基)的新型[羟基(甲苯磺酰氧基)碘]芳烃制备了带有N-甲苯磺酰基-4-吡唑基,3-三氟甲基苯基和3,5-双(三氟甲基)苯基作为芳香族基团的碘代芳烃。用这些化合物分别进行酮的α-甲苯磺酰化和α-磷酸酰化。将它们的反应性分别与母体[羟基(甲苯磺酰氧基)碘]苯和[羟基(磷酸甲酰氧基)碘]苯进行比较,因此将[羟基(甲苯磺酰氧基)碘]芳烃和[3]作为芳族基团的-三氟甲基苯基和3,5-双(三氟甲基)苯基显示出最佳的反应性。
