[reaction: see text] [corrected] Regio- and chemoselective reduction of nitroarenes and carbonylcompounds and reductive cleavage of azo compounds, including bulkier molecules, was achieved by the catalytictransfer hydrogenation method (CTH) using a novel nickel-containing mesoporous silicate (NiMCM-41) molecular sieve catalyst. In addition, the catalyst was also found to behave as a truly heterogeneous
