meta-Selective C–H nitration of phenol derivatives was developed using a Ru-catalyzed σ-activation strategy. Cu(NO3)2·3H2O was employed as the nitrating source, whereas Ru3(CO)12 was found to be the most suitable metal catalyst for the protocol.
使用Ru催化的σ-活化策略开发了对苯酚衍生物的meta-选择性C-H硝化反应。Cu(NO3)2·3H2O被用作硝化源,而Ru3(CO)12被发现是该方案中最适合的金属催化剂。
