Nickel-catalyzed cycloaddition of alkynes and 2-sulfobenzoic anhydrides gives highly functionalized thiochromenones. The reaction undergoes a deoxygenative rather than decarbonylative pathway and shows advantages of an excellent isolated yield (up to 95%), high reaction efficiency, and high regioselectivity. As one of the resulted products, 2,3-di(triphenylamine)-thiolchromenone possesses a typical aggregation-induced emission property and emits efficient near-infrared fluorescence.
镍催化的炔烃与2-磺基苯甲酸酐的环加成反应可生成高度官能化的硫代色烯酮。该反应经历的是脱氧途径而非脱羰途径，具有分离产率优异（高达95%）、反应效率高和区域选择性高的优点。作为所得产物之一，2,3-二（三苯胺）-硫代色烯酮具有典型的聚集诱导发光性质，并能发出高效的近红外荧光。
