The catalytic Baeyer–Villiger rearrangement of flavanones is described by the use of the homogeneous methyltrioxorhenium (MTO)/H2O2 system. In these experimental conditions 3,4-dihydro-4-phenyl-1,5-benzodioxepin-2-ones and previously not reported para-quinone derivatives have been obtained in mild experimental conditions from acceptable to good yields.
黄烷酮的催化拜耶-维利格重排反应是通过使用均相甲基三氧杂hen(MTO)/ H 2 O 2系统进行描述的。在这些实验条件下,已在温和的实验条件下从可接受的产率到良好的产率获得了3,4-二氢-4-苯基-1,5-苯并二氧杂-2-酮和先前未报道的对苯醌衍生物。
