reactions at room temperature continues to be a tough challenge. Use of a phosphonate linkage allowed a Pd (II)-catalyzed meta-C–H functionalization at room temperature while incorporating a cyanophenol-based directing moiety. Successful implementation of sequential di-meta-olefination led to the synthesis of a trialkenyl arene, which has applications in organic electronics and optoelectronics. Under robust
在室温下发展间位-C-H官能化反应仍然是一个艰巨的挑战。膦酸酯键的使用允许Pd(II)在室温下催化间位C–H官能化,同时引入基于氰基酚的导向部分。顺序二元间烯烃的成功实施导致了三烯基芳烃的合成,该三烯基芳烃已在有机电子学和光电子学中得到应用。在稳定的条件下,已经发现了C-O键形成的间位羟基化和间位乙酰氧基化。
