An efficient, straightforward and environmentally benign process has been developed for the synthesis of fluorenone and 1-tetralone derivatives using cyclic 1,3-dione, malononitrile and dialkylacetylenedicarboxylate as starting materials in aqueous medium. The reaction is favoured in presence of resorcin[4]arene which is effective as a reusable organocatalyst. The catalyst has been easily synthesized and characterized by ¹H, ¹³C NMR, IR, XRD and HRMS analyses. Resorcin[4]arene afforded the resulted products in a shorter time and in good yields. The recyclability of the catalyst was established up to 6th cycle by FT-IR and SEM images.

已经开发了一种有效的，直接的和环境友好的方法，该方法用于在水性介质中使用环状的1，3-二酮，丙二腈和二烷基乙酰二羧酸二甲酯作为起始原料来合成芴酮和1-四氢萘酮衍生物。在作为可重复使用的有机催化剂有效的间苯二酚[4]芳烃的存在下，该反应是有利的。该催化剂易于合成，并通过¹ H，¹³ C NMR，IR，XRD和HRMS分析进行表征。间苯二酚[4]芳烃以较短的时间和良好的收率提供了所得产物。通过FT-IR和SEM图像确定催化剂的可回收性直至第6个循环。
