Described herein is the iridium-catalyzed sequential C(2)-arylation reaction and intramolecular C–O bond formation from azulenecarboxylic acids and diaryliodonium salts, leading to the formation of 3-arylazulenofuranones. The sequential reaction proceeded smoothly through generation of 2-arylazulene-1-carboxylic acids derived from the iridium-catalyzed regioselective C(2)-arylation reaction without the decarboxylation reaction.

铱（III）催化的顺序C（2）-芳基化和Azulene羧酸和Diaryliodonium盐进入Azulenofuranones的分子内CO键形成。

本文描述的是铱催化的连续C（2）-芳基化反应以及由氮杂羧酸和二芳基碘鎓盐形成的分子内C-O键，从而导致3-芳基氮杂呋喃酮的形成。顺次反应通过产生自铱催化的区域选择性C（2）-芳基化反应而没有脱羧反应的2-芳基氮杂-1-羧酸而顺利进行。
