found to be effective for intramolecular C–H amination in water. With 2-azidobiphenyls as substrates, the reaction efficiently provided various carbazoles with N2 as the sole byproduct. The reaction showed high functional-group tolerance and could be used in the synthesis of several natural carbazole alkaloids. The catalytic process was promoted by water, and the reaction was inefficient in the organic
发现钯 (II) 催化对水中的分子内 C-H 胺化有效。以 2-叠氮联苯为底物,该反应有效地提供了各种咔唑,N2 作为唯一的副产物。该反应显示出高官能团耐受性,可用于合成多种天然咔唑生物碱。催化过程受水促进,在所研究的有机溶剂中反应效率低下。
