我们开发了一种硫嵌入环状π-延伸（thia-APEX）反应，可以一步在未官能化的芳烃上构建硫嵌入阳离子六方芳环--硫代吡喃鎓。thia-APEX的关键是使用S-酰亚胺化的邻芳酰基芳硫醇，并且可以容易地合成各种π-扩展的硫代吡喃鎓。合成的硫代吡喃鎓在可见光到近红外区域内表现出不同的吸收和发射特性，这取决于微小的结构差异。
We developed a sulfur-embedding annulative π-extension (thia-APEX) reaction that could construct a sulfur-embedding cationic hexagonal aromatic ring, thiopyrylium, onto unfunctionalized aromatics in one step. The key of thia-APEX is the use of S-imidated ortho-arenoyl arenethiols, and a variety of π-extended thiopyryliums can easily be synthesized. The synthesized thiopyryliums showed diverse absorption and emission properties over the visible light to NIR region, depending on minor structural differences.
