几十年来,已经报道了大量的醌类化合物的制备、性质和应用,四氯-1,4-苯醌(1)和2、3-二氯-1,4-萘醌(2)中的氯相当活泼,能和许多亲核试剂反应,如醇和酚;硫醇和硫酚;胺及许多含NH的杂环化合物。1和2与磷亲核试剂的反应也是已知的,本文报道1及2和芳碲基或烷碲基亲核试剂的反应。
It has been reported for decades that a large number of quinone compounds have been prepared, characterized and applied in tetrachloro-1,4-benzoquinone (1) and 2,3-dichloro-1,4-naphthoquinone Chlorine is quite reactive and can react with many nucleophiles such as alcohols and phenols; thiols and thiophenols; amines and many NH-containing heterocyclic compounds. The reaction of 1 and 2 with phosphorus nucleophiles is also known and the reactions of 1 and 2 with aryltellurine or alkanellide-based nucleophiles are reported herein.
