transition metals are necessary in the reaction of in situ generated arynes with nitrosoarenes to give substituted carbazoles. Depending on the fluoride source and the solvent, either N‐arylated carbazoles or NH‐carbazoles are obtained (see scheme; DME=dimethoxyethane, OTf=trifluoromethanesulfonate). In these cascades a CC and one or two CN bonds are formed. The reactions are easy to conduct and proceed
原位生成的芳烃与亚硝基芳烃反应生成取代的咔唑时,不需要过渡金属。根据氟化物来源和溶剂的不同,可以得到N-芳基化咔唑或NH-咔唑(参见方案; DME =二甲氧基乙烷,OTf =三氟甲磺酸盐)。在这些级联中,形成一个CC和一个或两个CN键。该反应易于进行并在温和条件下进行。
