their porosity, high internal surface area, and structural adaptability. Typical acetylation reactions of aldehydes require elevated temperatures and excess alcohol to drive the reactions to completion. In this current work, MOF-808 is used as a heterogeneous catalyst for acetylation of aldehydes in methanol using a mild photothermal process. Optimized conditions gave 72% yield of 2-(dimethoxymethyl)naphthalene
金属有机骨架(MOF)由于具有孔隙率,高内表面积和结构适应性,因此有望应用于催化领域。醛的典型乙酰化反应需要升高的温度和过量的醇以驱动反应完成。在当前的工作中,MOF-808用作非均相催化剂,使用温和的光热过程将甲醇中的醛进行乙酰化。优化条件在仅使用荧光灯的情况下,在10 mol%MOF-808的存在下,在45°C下得到2-(二甲氧基甲基)萘的产率为72%。MOF-808最多可循环使用5次,而不会降低催化活性。原理证明的衬底范围证明了对于芳族和脂族衬底的潜在实用性。
