摘要
芳基重氮盐在乙醇中的光热分解已有很多研究［１～７］，但分解产物及提出的分解机理不完全统一．就一般的观点，芳基重氮盐在光热的作用下可以采取异裂或均裂的分解方式，以苯基重氮盐为例，可表示如下：式中Ｘ－为Ｃｌ，ＨＳＯ４，ＢＦ４等负离子异裂产生芳基正离子中间...
he products of the
photochemical and thermal decompositions of diphenylamine4 diazonium salt (DDS),
3methoxydiphenylamine4diazonium salt (MODDS), Nmethyl diphenylamine4diazonium salt
(NMDDS), and carbazol3diazonium salt (CDS) in ethanol were investigated. It was shown that
the photochemical decomposition mainly produces ethoxy substituted product of corresponding
diazonium salt via the heterolytic cleavage of CN bond. The thermal decomposition, however,
produces only the reduced product via the homolytic cleavage of CN bond.\=
