H6[PMo9V3O40] was used as an efficient catalyst for the preparation of 1-aroyl-2-arylidene hydrazines. 2,5-Disubstituted 1,3,4-oxadiazoles have been synthesized by oxidation of 1-aroyl-2-arylidene hydrazines with CrO3 in excellent yields.
H 6 [PMo 9 V 3 O 40 ]被用作制备1-芳酰基-2-亚芳基肼的有效催化剂。已经通过用CrO 3氧化1-芳基-2-亚芳基肼以优异的产率合成了2,5-二取代的1,3,4-恶二唑。
