Various pyrazole-based P,N (2a-c) and N,N (3a-b) ligands have been synthesized. Using representative ligands, NiII, CoII, CuII, and CuI complexes have been prepared and structurally characterized by crystallogra
Pyrazole-tethered arylphosphine ligands for Suzuki reactions of aryl chlorides: How important is chelation?

Pyrazole-derived bidentate ligands (P,N-donor) with bulky substituents at the 3-position of the pyrazole, 1b-d, were used with Pd2(dba) 3 to carry out efficient Suzuki coupling reactions with both aryl bromides and chlorides. Enhanced catalytic activity on account of steric crowding in the metal complex suggested participation of a chelated structure in the intermediate catalytic steps.
