摘要/Abstract

摘要： 本文研究了β二酮类化合物与四氯苯醌在C₆D₆中的光诱导CIDNP现象.实验结果表明,β二酮类化合物与四氯苯醌在₆D₆中主要是四氯苯醌夺氢的反应.氢供体是由β二酮类化合物的主要存在形式来决定的.

关键词: β二酮类化合物, 四氯苯醌, CIDNP

Abstract: The reactions of three β-diketones with chloranil in C₆D₆ under UV irradiation were investigated by the chemically induced dynamic nuclear polarization(CIDNP).The results show that a hydrogen abstraction interaction between chloranil and β-diketones was involved. As a result, singlet multiplicity stable neutral radical pairs(RP) were formed, as intermediates,producing CIDNP polarizations.RP recombined to develop the new OH group of phenol polarizations of the recombination compounds.

Key words: β-diketones, chloranil, CIDNP
