2,3,4-三羟基苯乙酮腙类试剂的合成及其光谱研究

Synthesis of 2,3,4-Trihydroxyacetophenone Hydrazones and Study on Their Spectral Properties

用连苯三酚合成2,3,4三羟基苯乙酮,用苯甲酸乙酯、对羟基苯甲酸甲酯与水合肼反应,合成苯甲酰肼和对羟基苯甲酰肼,然后用2,3,4三羟基苯乙酮与苯甲酰肼、对羟基苯甲酰肼、苯肼反应,合成了三种新的2,3,4三羟基苯乙酮腙类试剂。研究了腙类试剂的红外光谱、紫外光谱、荧光光谱特性。

2, 3, 4-trihydroxyacetophenone was synthesized with pyrogallol. Benzoylhydrazone and p-hydroxybenzoylhydrazone were synthesized using the reaction of ethyl benzoate and methyl p-hydraxy benzoate with hydrazine hydrate. Three novel 2, 3, 4-trihydroxyacetophenone hydrazones were synthesized using the reaction of 2, 3, 4-trihydroxyacetophenone, with benzoylhydrazone, p-hydroxybenzoylhydrazone and phenylhydrazine. IR, UV and the fluorescence spectrum of 2,3,4-trihydroxyacetophenone hydrazones were studied.
