A palladium(0)-catalyzed ring-opening cross-coupling reaction between tert -cyclobutenols and aryl halides produces γ-arylated β,γ-unsaturated ketones. In the case of aryl halides bearing functional groups at the ortho position, the resulting ring-opened ketones undergo intramolecular condensation to afford bicyclic aromatic compounds.

钯催化环丁烯醇与芳基卤的开环偶联

钯（0）催化的叔环丁烯醇和芳基卤化物之间的开环交叉偶联反应产生γ-芳基化的β，γ-不饱和酮。在邻位带有官能团的芳基卤化物的情况下，所得开环酮进行分子内缩合以提供双环芳族化合物。
