The title compounds (3) have been prepared and their chemical properties studied. With iodine they give aryloxymethyl aryloxyacetates (4) through the intermediacy of aryloxyacetyl hypoiodites and α-iodoanisoles. The former are unstable but have been trapped with pyridine to give N-iodopyridinium aryloxyacetates, whereas the latter are stable and react independently with compounds (3) to afford the
已经制备了标题化合物(3)并研究了它们的
化学性质。与
碘一起,它们通过芳氧基乙酰基次
碘酸盐和α-
碘苯甲醚的中间体得到芳氧基甲基芳氧基
乙酸酯(4)。前者是不稳定的,但已被
吡啶截留,得到N-
碘吡啶鎓的芳氧基
乙酸盐,而后者是稳定的,并与化合物(3)独立反应,得到
乙酸盐(4)。已经研究了(3)的热分解,并且除了酯(4)之外,还形成了芳基芳氧基
乙酸酯。简要讨论了热分解的机理。
