The palladium-catalyzed chemoselective mono-amination of dichlorobenzenes was reported in this paper. Under the suitable conditions, all reactions involving the three isomers of dichlorobenzenes with various secondary and primary amines in the presence of a well-defined N-heterocyclic carbene-palladium(II)-2-methyl-4,5-dihydrooxazole complex, gave the desired mono-aminated products in moderate to high yields as the major or sole one.

N-杂环卡宾-Pd（II）-2-甲基-4,5-二氢恶唑配合物催化的二氯苯高化学选择性单胺化

本文报道了钯催化的二氯苯化学选择性单胺化反应。在合适的条件下，在明确定义的N-杂环卡宾-钯（II）-2-甲基-4,5-二氢恶唑络合物的存在下，所有涉及二氯苯的三种异构体与各种仲胺和伯胺的反应均得到所需的单胺化产品，以中等或高收率作为主要或唯一一种。
