The synthesis of gold(I) complexes of the type LAuR (L
= PCy3, IPr; R = aryl; IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene)
starting from LAuX (X = Br, OAc) and boronic acids in the presence
of Cs2CO3 has been investigated. The reactions
proceed smoothly in good to excellent yields over the course of 24–48
h in isopropyl alcohol at 50–55 °C. The aryl groups include
a variety of functionalities and steric bulk, and in two cases, are
heterocyclic. All of the products have been characterized by multinuclear
NMR spectroscopy and elemental analysis and most by X-ray crystallography.
This work affirms that, almost without exception, base-assisted auration
is a useful and reliable way to form gold–carbon bonds.
