The above article, published online on 04 August 2011 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the journal Editor-in-Chief, Sandra Gonzalez Gallardo; and Wiley-VCH GmbH. The retraction has been agreed upon following an investigation based on concerns raised by a third party. The investigation revealed that several 1H NMR spectra presented in the supporting information of this article, including those corresponding to entries 2, 5, 6, and 16 of Table 1, have been duplicated from a publicly available database. The authors were unable to provide their raw data or a satisfactory explanation. The editors consider the results and conclusions of this article unreliable. The authors were informed of the retraction.

Author contribution statement

This is a collaborative research work between IIP Dehradun and IACS Kolkata. The synthesis of PMO material and its characterization were done by the IACS group, whereas catalysis and NMR analysis of the products were done by IIP group. Mahasweta Nandi, Arindam Modak and Asim Bhaumik of IACS Kolkata provided the support material and they neither did the catalysis nor the 1H NMR analysis of the reaction products as presented in Table 1.
