Lanthanide-organic framework (LnMOF) [Eu-2(MELL)(H2O)(6)] (1) was rapidly produced via microwave-assisted hydrothermal synthesis and its performance as heterogeneous catalyst for the cyanosilylation of aldehydes was investigated. The catalytic assays were performed with different aldehydes and solvents using as-prepared and thermally active (100 degrees C for 1 h) LnMOF material, and the results show that (1) acts as an excellent catalyst for the addition of trimethylsilyl cyanide to aldehydes with short reaction times and excellent yields. In addition, the catalyst was recycled and recovered in the addition reaction of TMSCN to 2-furfuraldehyde without loss of activity. (C) 2013 Elsevier B.V. All rights reserved.
