Multinuclear Zn(II)-arylhydrazone complexes as catalysts for cyanosilylation of aldehydes

Three known multinuclear Zn(II)-arylhydrazone complexes, [Zn{(CH3)2SO}(H2O)(L1)] (1), [Zn2(CH3OH)2(μ-L2)2] (2) and [Zn4(μ-OH)2(1κO:2κO-HL3)4(κO-HL3)2(H2O)4] (3) were prepared upon reaction of ZnCl2 or Zn(CH3COO)2·2H2O with 3-(2-(2-hydroxy-4-nitrophenyl) hydrazineylidene) pentane-2,4-dione (H2L1), 3-(2-(2-hydroxyphenyl)hydrazineylidene)pentane-2,4-dione (H2L2) and 2-(2-(2,4-dioxopentan-3-ylidene)hydrazineyl)benzoic acid (H2L3), respectively, in methanol solution. Compounds 1–3 were tested as catalysts for the cyanosilylation reaction of a diversity of both aliphatic and aromatic aldehydes with trimethylsilyl cyanide yielding the corresponding cyanohydrin trimethylsilyl ethers in high yields (72–98%) in methanol and at room temperature. © 2020 Elsevier B.V.
