cascade dehydrogenative cyclization of N-tosyl-8-ethynyl-1-naphthylamines under air is described herein for the synthesis of thioazafluoranthenes. The reaction proceeds smoothly with high efficiency and a broad reaction scope. The product is indeed a new fluorophore and its photophysical properties are also investigated. Based on the results, we are pleased to find that the Stokes shift of amino-linked
本文描述了N-甲苯磺酰基-8-乙炔基-1-萘胺在空气下的铜催化的自由基级联脱氢环化反应,用于合成硫杂氮杂蒽。反应平稳高效地进行,反应范围广。该产品确实是一种新的荧光团,还对其光物理性质进行了研究。根据结果,我们很高兴地发现,稀释的四氢呋喃中氨基连接的硫杂氮杂荧蒽的斯托克斯位移确定为143 nm(4830 cm –1)。
