well-defined hydride Fe(II) PNP pincer complex has been prepared, structurally characterized, and used as catalyst in the hydrogenation of aldehydes to alcohols. The new SILP catalyst, with the optimum pore filling, was highly active exhibiting TONs and TOFs of up to 1000 and 4000 h–1, respectively, under mild conditions (25 °C, 10–50 bar H2 pressure) without significant leaching of both the complex and the IL
制备了一种碱耐受性支持的离子液相(SILP)系统,该系统包含定义明确的氢化物Fe(II)PNP钳形配合物,并进行了结构表征,并用作醛加氢制醇的催化剂。新型SILP催化剂具有最佳的孔填充性能,在温和条件(25°C,10–50 bar H 2压力)下,TONs和TOF分别高达1000 h和4000 h –1时表现出很高的活性,并且没有明显的溶出。复合体和IL。
