X-ray characterization of triphenylphosphine-gold(I) olefin pi-complexes and the revision of their stability in solution
2017
Abstrakt
A large number of cationic Au(I) pi-complexes have been reported in the literature. However, a single Xray structure of genuine [Au(PPh3)(hydrocarbon)](+) pi-complex without any additional stabilization has not been published so far.
We present herein isolation and X-ray characterization of several complexes of this type. Also, we show that these pi-complexes are more stable than previously reported and we investigate different modes of activation of the [Au(PPh3)] Cl precatalyst on their stability in solution.
