摘要：
Single, double, triple: Highly selective double H atom abstraction (HAA) from ethane and triple HAA from n-butane by AuNbO3+ clusters have been characterized by mass spectrometry and DFT calculations. The multiple HAAs are initiated by oxygen-centered radicals and promoted by gold. The gold atoms act as electron acceptors during the triple HAAs and help to store a pair of valence electrons between Au and Nb atoms (see picture). Copyright © 2013 WILEY-VCH Verlag GmbH & Co.
