π Complexes of P^P and P^N chelated gold(i)†
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^N complex is a competent catalyst for indole alkylation. The reaction proceeds with complete C3 and Markovnikov selectivity.
