摘要：

Controversy resolved! A combination of gas-phase ion-molecule reactions and theoretical studies confirm bisligated mononuclear Au I complexes are unable to undergo oxidative addition of iodobenzene for Sonogashira coupling, but that the ligated gold clusters [Au 3L n] + (L=Ph 2P(CH 2) nPPh 2; n=3-6) activate the C-I bond. DFT calculations on the transition states show that the linker size n tunes the cluster reactivity. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
