One for all: The coupling of a range of nitrogen‐ and sulfur‐containing heteroaryl halides with five‐membered nitrogen‐, oxygen‐, and sulfur‐containing heteroaryl boronic acids were achieved in high yields with only 0.5 mol % of the single‐component nickel precatalyst [(dppf)NiCl(cinnamyl)] (dppf=1,1′‐bis(diphenylphosphanyl)ferrocene). The reaction demonstrates good functional group compatibility,
一劳永逸:一系列含氮和硫的杂芳基卤化物与五元含氮、氧和硫杂芳基硼酸的偶联以高产率实现,单组分仅为 0.5 mol%镍预催化剂 [(dppf)NiCl(肉桂基)] (dppf=1,1'-双(二苯基膦基)二茂铁)。该反应具有良好的官能团相容性,无需干燥箱即可大规模进行。
