Synthesis of Xanthene-1, 8(2H)-diones Under Solvent-free Condition Catalyzed by Boric Acid
摘要/Abstract
摘要:
在无溶剂研磨条件下,以硼酸为催化剂由芳香醛与1,3-环己二酮衍生物制备了9-芳基-1,8-二氧代八氢化氧杂蒽衍生物.此方法具有对环境友好、收率高、操作方便等优点.
Abstract:
9-ary- l 3, 4, 5, 6, 7, 9 -hexahydro -1H -xanthene -1,8(2H)-diones are synthesized from aromatic alde-hydes and 1,3-cyclohexadione under grinding condition catalyzed by boric acid. This method has the advantages of simple manipulation, high yields and environment -friendly.
