These intramolecular C-H insertion reactions were performed in excellent chemical selectivity to only afford intramolecular C-H insertion products without any Wolff rearrangement products. 这个反应具有很好的化学选择性,只形成分子内C-H插入产物,没有观察到任何Wolff重排产物。
Both competitive intramolecular and intermolecular reactions for benzyl alcohols in the presence of aliphatic alcohols indicate high selectivity ( 8 examples). 大量分子内及分子间竞争实验表明,该氯代方法对于苄醇具有高度的化学选择性(8个例子)。
