1 Retraction note to: Catalysis Letters (2013) 143:1277–1284 https://doi.org/10.1007/s10562-013-1063-x

The Editor in Chief has retracted this article. After publication, concerns were raised because the top panel of Scheme 3 in this article seems to overlap with the bottom-left panel of Fig. 1 in article [1] by the same research group that was simultaneously in submission to a different journal, and Fig. 1 appears to correspond to Fig. 2 in [1]. Additionally, there are textual overlaps with articles by the same authors [2, 3] that were simultaneously in submission and a previously-published article by different authors [4]. Therefore, the Editor in Chief has lost confidence in the integrity of the findings. All authors disagree with this retraction.
