This was demonstrated with general and efficient syntheses of sterically hindered (hetero)biaryls (see examples shown), mild coupling reactions of alkyl boron derivatives, and rapid coupling reactions of aryl chlorides at room temperature.

However, success with this substrate rarely translates into similiar levels of activity or generality with even slightly more hindered or functionalized substrates.

Soc. 2003, 125, 16 194; 9eThe best previous results for this reaction are described in ref. [2c], although no yield of isolated product is reported. 10The half-life was determined by GC analysis. 11While exceedingly high turnover numbers have been realized for the coupling of phenyl boronic acid with 4-bromoacetophenone, this is a particularly trivial process and does not extend to the efficient coupling of unactivated and ortho-substituted substrates at low catalyst levels. We have previously shown this reaction to proceed even in the absence of added ligand and recommend that it not be used as a benchmark to test new catalysts, see ref. [7a]. 12For a recent report describing the cross-coupling of aryl chlorides with alkyl boronic acids, see: N. Kataoka, Q. Shelby, J. P. Stambuli, J. F. Hartwig, J. Org. Chem. 2002, 67, 5553.

Data processed using the program SAINT supplied by Siemens Industrial Automation, Inc., structure determination by direct methods (SHELXTL V6.10, G. M. Sheldrick, University of Göttingen, and Siemens Industrial Automation, Inc.), structure refined on F2 by full-matrix least-squares methods, absorption correction applied with SADABS. All non-hydrogen atoms were refined anisotropically. All hydrogen atoms were located in the electron density map and refined isotropically. The refinement of 435 parameters using 5293 reflections and 0 restraints gave R1=0.0286, wR2=0.0676 (I>2σ(I) data), goodness of fit on F2=1.052, Δρmax/min=0.509/−0.338 e Å−3.

R. Strieter, S. L. Buchwald, unpublished results) cast doubt on this explanation of the high level of catalytic activity manifested with 1.
