Worth its salt: The palladium‐catalyzed decarboxylative coupling of the cyanoacetate salt as well as its mono‐ and disubstituted derivatives with aryl chlorides, bromides, and triflates is described (see scheme). This reaction is potentially useful for the preparation of a diverse array of α‐aryl nitriles and has good functional group tolerance. S‐Phos=2‐(2,6‐dimethoxybiphenyl)dicyclohexylphosphine)
值得其盐:描述了氰基乙酸盐及其与芳基氯化物,溴化物和三氟甲磺酸酯的钯催化的脱羧偶联反应(参见方案)。该反应对于制备各种α-芳基腈具有潜在的实用性,并具有良好的官能团耐受性。S-Phos = 2-((2,6-二甲氧基联苯)二环己基膦),Xant-Phos = 4,5-双(二苯基膦基)-9,9-二甲基x吨。
