aminocarbonylation of aryl and heteroaryl sp2 C−H bonds using nitroarenes as the nitrogen source was achieved using Mo(CO)6 as the reductant and origin of the CO. This intermolecular C−H bond functionalization does not requires any exogenous ligand to be added, and our mechanism experiments indicate that the palladacycle catalyst serves two roles in the aminocarbonylation reaction: reduce the nitroarene
Mo(CO)6作为CO的还原剂和来源,使用硝基芳烃作为氮源,实现了三组分钯催化的芳基和杂芳基sp 2 CH键的氨基羰基氨基羰基化反应。要求添加任何外源配体,我们的机理实验表明,戊四环催化剂在氨基羰基化反应中起两个作用:将硝基芳烃还原为亚硝基芳烃并激活sp 2 CH键。
