title: A Stable Porphyrin-Based Porous mog Metal-Organic Framework as an Efficient Solvent-Free Catalyst for C-C Bond Formation.
abstract: We herein report the porous 4-fold interpenetrated mog (moganite) metal-organic framework (MOF) [Cd3(tipp)(bpdc)2]·DMA·9H2O (1·Cd; H2tipp = 5,10,15,20-tetrakis(4-(imidazol-1-yl)phenyl)porphyrin, H2bpdc = biphenyl-4,4'-dicarboxylic acid, DMA = N,N'-dimethylacetamide). The incorporation of Cd and carboxylate oxygen affords 1·Cd rich Lewis acid and basic sites. This MOF 1·Cd was then applied as an efficient heterogeneous catalyst for the important cyanosilylation of aldehydes and Knoevenagel condensation reactions. 1·Cd features excellent catalytic performance and recyclability for the cyanosilylation of various aldehydes with trimethylsilyl cyanide (TMSCN). Moreover, 1·Cd shows highly efficient catalysis and substrate selectivity for Knoevenagel condensation reactions of various aldehydes with malononitrile. The high catalytic activity and stability toward C-C bond formation make 1·Cd a promising heterogeneous catalyst.
