The activation of the inert CO bonds in mesylates through the use of a new class of imidazolyl phosphines allows the decarboxylative coupling of aryl mesylates as well as polysubstituted alkenyl mesylates. Variation of the ligands leads to two complementary methods providing the corresponding biaryls and polysubstituted olefins in good yields.
通过使用一类新的咪唑基膦来活化甲磺酸酯中的惰性CO键,可以使甲磺酸甲磺酸酯和多取代的烯基甲磺酸酯进行脱羧偶联。配体的变化导致两种互补方法以良好的产率提供相应的联芳基和多取代的烯烃。
