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,

C1–C5, bearing dianisole backbones and substituted N-aryl moieties have been synthesized and characterized. The electronic effect as well as the steric environment of the NHC ligands has been assessed. The synthesized palladium complexes were applied for Suzuki–Miyaura cross-coupling reactions under aerobic conditions. The relationship between the catalytic structure and catalytic performance was then

halides) by either thermal or photochemical activation. We have applied this general reaction scheme to the development of a phosphorescence-based sensing system for cyanogen halides. To carry out structure-property relationship studies, a series of previously unreported Pt(II) complexes was prepared. Most of the complexes (excluding those that incorporated substituents on the ligands that forced steric
