Abstract Friedel-Crafts type reactions of phenol derivatives with some cyclic ketones such as ninhydrin (1), alloxan (2), isatin (3), and parabanic acid (4) were examined. 2-Monoaryl- and 2,2-diaryl-1,3-indanedione derivatives were obtained depending on the acid catalyst in the cases of ninhydrin and alloxan. In the case of isatin, the corresponding diarylated derivative was obtained as the sole product
摘要 研究了苯酚衍生物与一些环酮如茚三酮 (1)、四氧嘧啶 (2)、靛红 (3) 和对羟基苯甲酸 (4) 的 Friedel-Crafts 型反应。在茚三酮和四氧嘧啶的情况下,取决于酸催化剂,获得了 2-单芳基-和 2,2-二芳基-1,3-茚二酮衍生物。在靛红的情况下,相应的二芳基化衍生物作为唯一产物以高产率获得。对羟基苯甲酸在反应条件下不反应。
