2,3-Naphthoquinodimethanes are easily generated from o-bis(α-acetoxypropargyl)benzene derivatives with SmI2 in the presence of palladium catalyst under mild conditions. The reactions of the quinodimethane intermediates were found to follow the different paths depending on the acetylenic substituents of substrates.
在钯催化剂的存在下,在温和的条件下,由邻双(α-乙酰氧基炔丙基)苯衍生物与SmI 2容易生成2,3-萘醌二甲烷。发现奎尼二甲烷中间体的反应遵循不同的途径,这取决于底物的炔基取代基。
