Two scandium coordination polymers: rapid synthesis and catalytic properties

Abstract

Two scandium coordination polymers (Sc-CPs), [Sc(L1)2(DMF)] (DMF = N,N′-dimethyl formamide, H2L1 = pyrazine-2,3-dicarboxylic acid) (1) and [Sc(L2)(C2O4)0.5(H2O)2]·H2O (H2L2 = pyrazine-2,5-dicarboxylic acid) (2), were prepared via hydrothermal and microwave (MW) heating techniques. It is noted that MW heating can effectively accelerate the reaction compared with a conventional hydrothermal method and decrease the crystal size of the samples. 1 shows a 1D non-planar double chain, while 2 exhibits a brick-like 2D network. After activation, 1 and 2 exhibit good catalytic performance for the cyanosilylation reaction of aromatic aldehydes; in addition, the catalysts prepared by the MW method exhibit better catalytic activity compared with those synthesized by the conventional hydrothermal method.
