4-oxypyridines, and 3-iodo-2,4-oxyquinolines with arylboronic acids are described as a useful and efficient alternative to homogeneous conditions. The methodology features ligand-free and environmentally friendly conditions, and tolerates a wide range of boronic acids. The cross-coupled products can be viewed as useful intermediates for the preparation of 3-aryl-4-hydroxypyridin-2(1H)-ones, which can be used
3-iodo-4-oxypyridin-2(1H)-ones、3-iodo-2,4-oxypyridines 和 3-iodo-2,4-oxyquinolines 的实际多相 Pd/C 催化 Suzuki-Miyaura 交叉偶联反应芳基
硼酸被描述为均相条件的有用且有效的替代方法。该方法的特点是无
