Scheme 1.

Scheme 1.

Synthesis (two routes) and X-ray structure of the (P,NH+) gold(I) complex 2 derived from MeDalPhos. Thermal ellipsoids are drawn at 50% probability; the TfO counteranion and H atoms, except for that on nitrogen, are omitted for clarity. Selected bond lengths (Å) and bond angles (°): P–Au 2.270(1), Au–Cl 2.283(1), Au∙∙∙H 2.24(3), P–Au–Cl 176.98(2), N–H∙∙∙Au 165(2).
