An efficient metal-free approach to 2-aryloxybenzofuranonefuran-3(2 H )-ones has been developed. Using tert -butyl hydroperoxide as oxidant and tetrabutylammonium iodide as catalyst, 2-acylphenols reacted with phenols to provide 2-aminobenzofuran-3(2 H )-one derivatives in moderate to good yields.
已开发出一种有效的无金属方法来制备 2-芳氧基苯并呋喃酮呋喃-3(2 H )-ones。使用叔丁基氢过氧化物作为氧化剂和四丁基碘化铵作为催化剂,2-酰基苯酚与苯酚反应以中等至良好的产率提供2-氨基苯并呋喃-3(2 H )-酮衍生物。
