| Abstract |
The novel Ag(I) and Cu(II) coordination polymers [Ag((3)-1O;2:3O;4N-HL)](n).n/2H(2)O (1) and [Cu(en)(2)(-1O;2N-L)](n).nH(2)O (2) [HL- = 2-(2-(1-cyano-2-oxopropylidene)hydrazinyl)benzene sulfonate] were synthesized and characterized by IR and ESI-MS spectroscopies, elemental and single crystal X-ray diffraction analyses. Compounds 1 and 2 as well as the already known complex salt [Cu(H2O)(2)(en)(2)](HL)(2) (3) have been tested as homogenous catalysts for the cyanosilylation reaction of different aldehydes with trimethylsilyl cyanide, to provide cyanohydrin trimethylsilyl ethers. Coordination polymer 2 was found to be the most efficient one, with yields ranging from 76 to 88\% in methanol, which increases up to 99\% by addition of the ionic liquid [DHTMG][L-Lactate]. |
