10. In the case of 2, a small amount (ca. 10%) of the 9,10-diphenyl substituted species (2″) was consistently observed, the structure of which was confirmed by NMR, mass spectrometry, and X-ray crystallography (see Figure S3, Supporting Information). At present, we do not know how this compound is formed; ongoing mechanistic experiments suggest that solvent does not play a significant role, that the process is not influenced by adventitious HCl, and that residual palladium in the pyridine compound is likely not involved.
