functional groups such as ether, ester, ketone, aldehyde, cyano, and unprotected amino and hydroxy groups. Finally, the potential utilization of the methodology was further demonstrated by the gram‐scalesynthesis of several core structures of commercialized antihypertensive drugs and fungicides. Thus, the combination of high activity, broad applicability, cheapness, and high stability of NiCl2(dppp)
Highly Efficient Suzuki-Miyaura Coupling of Aryl Tosylates and Mesylates Catalyzed by Stable, Cost-Effective [1,3-Bis(diphenylphosphino)propane]nickel(II) Chloride [Ni(dppp)Cl2] with only 1 mol% Loading

We present a highly active, inexpensive, universally applicable, and markedly stable [1,3-bis(diphenylphosphino)propane]nickel(II) chloride [Ni(dppp)Cl2] catalyst that is capable of effecting the Suzuki–Miyaura cross-coupling of the inherently less reactive but readily available aryl tosylates and mesylates with only 1 mol% loading and in the absence of extra supporting ligand. Under the optimized

towards a wide range of both phenols and boronicacids, including activated, nonactivated, deactivated, and heteroaromatic coupling partners. In addition, various functional groups, such as ether, amino, cyano, ester, and ketone groups, are compatible with this transformation. Notably, arylboronic acids containing an unprotected NH2 group and 2‐heterocyclic boronicacids, which are generally problematic
