with commercially available aromatic sulfonyl chlorides that function as an aryl group donor. The reaction tolerates a broad range of functional groups, including bromide and iodide, nitrile, ketone, and nitro groups. The reaction allowed the synthesis of polycyclic aromatic hydrocarbons, such as a bis(indene), indacene, and fused polyarene derivatives, some of them showing strong fluorescence in solution
多种多取代的 1H-茚可以通过铜催化的简单芳炔与用作芳基供体的市售芳族磺酰氯的芳基化环化反应来制备。该反应耐受广泛的官能团,包括溴化物和碘化物、腈、酮和硝基。该反应允许合成多环芳烃,例如双(茚)、茚和稠合聚芳烃衍生物,其中一些在溶液和固态中显示出强烈的荧光。
