Palladium(II) complexes containing bidentate cyclometalated C∼N chelating ligands are shown to react with PhINTs at room temperature to insert “NTs” into the Pd−C bond. This “NTs” insertion reaction has been applied to palladacyclic complexes of azobenzene, benzo[h]quinoline, and 8-ethylquinoline. The newly aminated organic ligands can be liberated from the metal center by protonolysis with trifluoroacetic
含有二齿环金属化的C〜N螯合配体的钯(II)配合物在室温下与PhNTs反应,将“ NTs”插入Pd-C键中。该“ NTs”插入反应已应用于偶氮苯,苯并[ h ]喹啉和8-乙基喹啉的四环配合物。新胺化的有机配体可以通过用三氟乙酸或HCl进行质子分解而从金属中心释放出来。
