A highly efficient, practical, and ligand-free palladium-catalyzed carbonylation of aryliodides with alkenylboronic acids has been developed. A variety of chalcones and α-branched enones were isolated in satisfactory to good yields with good substrate compatibilities under an ambient pressure of CO at room temperature. Moreover, the transformation proceeds well in the presence of a substoichiometric
开发了一种高效、实用且无配体的钯催化芳基碘与烯基硼酸的羰基化反应。在室温和 CO2 环境压力下,各种查尔酮和 α-支链烯酮的分离结果令人满意,产率良好,底物相容性好。此外,在存在亚化学计量量的碱的情况下,转化进行得很好。该策略作为后期功能化平台的优点已通过对源自雌酮和 3-苯基- 的复杂底物的修饰得到证明升-丙氨酸。
