The hemilabile P^N ligand MeDalphos enables access to a wide range of stable gold(i) π-complexes with unbiased alkenes and alkynes, as well as electron-rich alkenes and for the first time electron-poor ones.
Tricoordinate gold(I) π-complexes containing P-based chelating ligands (P^P and P^N) were prepared. The structure of the gold(I) styrene complexes has been analysed in detail based on NMR and XRD data. The P^Ncomplex is a competent catalyst for indole alkylation. The reaction proceeds with complete C3 and Markovnikov selectivity.
The oxidativeaddition of strained CC bonds (biphenylene, benzocyclobutenone) to DPCb (diphosphino‐carborane) gold(I) complexes is reported. The resulting cationic organogold(III) complexes have been isolated and fully characterized. Experimental conditions can be adjusted to obtain selectively acyl gold(III) complexes resulting from oxidativeaddition of either the C(aryl)C(O) or C(alkyl)C(O) bond
