A practical and greener method of the cross-coupling of vinylethylene carbonates (VECs) with arylboronic acids has been described. The coupling reaction was catalyzed by in situ generated palladium nanoparticles (PdNPs) without any ligands and additional stabilizers in water under ambient conditions to provide useful 4-hydroxylprenylarenes and their derivatives in good to high yields.
已经描述了一种实用且较绿色的碳酸乙烯基亚乙酯碳酸酯(VEC)与芳基硼酸的交叉偶联方法。在环境条件下,在水中通过原位生成的钯纳米粒子(PdNPs)催化,无需任何配体和其他稳定剂,即可催化偶联反应,从而以高至高收率提供有用的4-羟基戊烯基芳烃及其衍生物。
