TL;DR: In this paper, the gold-and palladium-catalysed cross-coupling reactions were investigated on two substrates containing an aryl iodide and an allenoate ester.

TL;DR: The in situ extended X-ray absorption fine structure study of the reactions indicated that the reaction mixtures contained only mononuclear gold species, the first proof for a homogeneous gold-catalysed oxidation reaction.

TL;DR: In this paper, the same authors reported that the same vinyl AuI intermediate is capable of producing the observed products under photolytic and thermal conditions, without the need for an additional photo(redox) catalyst under aerobic conditions.

TL;DR: The mechanistic studies show an allylic inversion, as supported by NMR data and an X-ray crystal structure analysis, as well as an intermolecular reaction, as determined by crossover experiments and clearly indicate product formation by a [3,3]sigmatropic rearrangement in the step forming the new C-C bond.

TL;DR: In this paper, the reaction proceeds under mild conditions which are crucial as harsher conditions would not be tolerated due to the high degree of conjugation in the products, which is crucial for the reaction.
