Annulated arenes and hetarenes were prepared in good to very good yields by hydriodic acid/red phosphorus mediated reductive cyclization of 3-(hetero)aryl phthalides. The reductive cyclization also proceeded successfully with 2-aroylbenzoic acids and 2-aroylnaphthoic acids.

Synthesis of symmetrical and unsymmetrical naphth-annelated thienyl heterocycles has been achieved via thionation of hydroxyketones/diketones using Lawesson's reagent. Photophysical studies of 1,3-disubstituted naphtho[c]thiopheneanalogs are presented. Electro-oxidative behavior of these naphtha-annelated thiophenes are investigated using cyclic voltammeter.
通过使用Lawesson试剂对羟基酮/二酮进行硫磺化,已经完成了对称和不对称的萘环化噻吩基杂环的合成。提出了1,3-二取代萘[ c ]噻吩类似物的光物理研究。使用循环伏安法研究了这些石脑油-退火噻吩的电氧化行为。
