Intramolecular CO bond forming reactions of aryl 2‐bromobenzyl ketones lead to benzo[b]furans. The cyclizations can be catalyzed by 10 mol% of iron trichloride (of 98% or of 99.995% purity) or sub‐mol% quantities of copper(II) chloride (of 99.995% purity).
芳基2-溴苄基酮的分子内CO键形成反应导致苯并[ b ]呋喃。10 mol%的三氯化铁(纯度为98%或99.995%)或亚摩尔%的氯化铜(II)(纯度为99.995%)可以催化环化反应。
