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, and is easily conducted on a large scale without a dry box.
