摘要

以噻唑环主链上具有3-甲基取代基和4-(2-羟乙基)取代基的硫胺素类似物为原料,在温和条件下通过转金属反应一步合成了单齿Ru(II)-噻唑酰基配合物。这些新型配合物在水中的5:2 HCO2H/NEt3缓冲液中通过转移加氢催化酮和醛转化为醇。然而,它们的效率远低于硫胺素衍生的双齿Ru(II)配合物,这强烈表明“N−H”在反应中起着至关重要的作用。

Synthesis and Characterization of Ru(II)−NSHC Catalysts Bearing Thiamine Analogs in Water-Solvent Transfer Hydrogenation Catalysis

Thiamine analogues with 3-methyl and 4-(2-hydroxyethyl) substituents on the backbone of thiazole ring, were used to synthesize monodentate Ru(II)-thiazolylidene complexes in a single step via transmetalation under mild conditions. These novel complexes catalyze the conversion of ketones and aldehydes to alcohols by transfer hydrogenation in a 5 : 2 HCO2H/NEt3 buffer in water. However, their efficiency was found to be much lower than the thiamine-derived bidentate Ru(II) complexes, which strongly indicates that the ‘N−H’ plays a crucial role in the reaction.
