摘要:脂肪族pnp夹钳负载的地球上富集的锰(i)二羰基配合物可作为有效的催化剂,用于在无碱条件下将多种醇与酯进行无受体脱氢偶联.反应在纯净的条件下进行,催化剂负载适中,仅释放出h 2作为副产物.通过合成与催化循环有关的关键物质(通过x射线结构测定,多核(1 H,13 C,31 P,15 N,55Mn)NMR,红外光谱等),方法是研究与假定机理相关的基本步骤,并借助dft计算.与相关的钌和铁pnp催化剂一样,脱氢是由pnp-Mn(co)2支架的酰胺基和氨基氢化物形式之间的循环而引起的.对于将醇脱氢成醛,我们的结果表明,最高的能垒对应于氨基氢化物形式的氢释放,尽管其值接近于醇的外球脱氢成醛的值.这与钌和铁的催化体系形成鲜明对比,在钌和铁的催化体系中,与金属-配体协同作用中释放出的氢相比,将底物脱氢成醛的能源需求更少.
