A palladium-catalyzed annulative π-extension reaction of bay-iodinated triphenylenes with aryliodides/o-chloroaromatic carboxylic acids was developed. This approach enabled the synthesis of diverse polycyclic aromatic compounds, including dibenzo[fg,op]tetracenes, azadibenzo[fg,op]tetracenes, and tribenzo[a,g,m]coronenes. Initial studies indicate that the resulting product, 2,3,8,9,14,15-hexakis(decyloxy)tribenzo[a
开发了一种钯催化的湾碘化苯并菲与芳基碘化物/邻氯芳香族羧酸的环π-延伸反应。这种方法能够合成多种多环芳香族化合物,包括二苯并[ fg , op ]并四苯、氮杂二苯并[ fg , op ]并四苯和三苯并[ a , g , m ]晕苯。初步研究表明,所得产物2,3,8,9,14,15-六(癸氧基)三苯并[ a , g , m ]晕苯表现出良好的液晶性质。
