    • n (1). These results suggest that 1a is formed in solution via ligand exchange and then rapidly decomposes to free pyridine and 1. This is completely consistent with our other data on the stability of 1a. Other workers have previously shown that treatment of DMAP-containing complexes with protonated pyridine leads to protonation of the more basic DMAP ligand and coordination of the Py donor group.

    • We also obtained the crystal structure of 1b (see the Supporting Information). While we were readily able to determine the connectivity of 1b, we have been unable to satisfactorily refine the data, despite collecting multiple data sets from several different crystals of reasonable quality. In all cases twinning was observed, which led to poor-quality diffraction data. As observed with the other structures, 1b is a neutral linear two-coordinate complex that dimerizes in the solid state. In this case the formation of the dimer is stabilized by an Au(I)-Au(I) interaction (Au-Au distance 3.19 Å)

    • To simplify the calculation, the polymeric gold precursor 1 was approximated by a tetrameric complex where the gold atoms bind end-on to the alkyne group of a neighboring complex to give a square arrangement (see the Supporting Information)
