摘要：

The gold(I)-mediated reaction between an internal alkyne and methanol proceeds by a dual activation mechanism, which directly results in formation of gem-diaurated intermediates. Reaction intermediates were investigated by IR multiphoton dissociation spectroscopy, kinetics by NMR spectroscopy, and the mechanism by DFT calculations. Copyright © 2012 WILEY-VCH Verlag GmbH & Co.
