中文摘要 乙酰丙酸（LA）催化轉移加氫（CTH）成為通用平台化學品γ-戊內酯（GVL）受到越來越多的關注，因為CTH可以使用醇作為氫供體和非貴金屬催化劑來實施。儘管常規加熱通常通過CTH用於LA轉化，但首次使用微波輻射（MWI）使用UiO-66作為非貴金屬催化劑通過CTH將LA轉化為GVL。與常規加熱相比，MWI顯著加速了LA向GVL的轉化，因為其收率和選擇性遠高於常規加熱所獲得的產率和選擇性。這種增強可能是因為在MWI下，UiO-66的Zr-O團簇具有快速且密集的熱量和促進作用，因此具有更強的催化活性。此外，MWI仍然能夠在不太適合用於LA的醇中大大提高LA的轉化率，並使不利的UiO-66-NH2發揮作用，並使有效的催化劑（如UiO-66-SO3H）具有更高的催化活性。這些特徵表明，MWI當然是通過CTH增強LA轉換的有用且有效的方法。這項研究的發現也是通過CTH和MWI開發高效LA轉化的重要基礎。
英文摘要 Catalytic transfer hydrogenation (CTH) of levulinic acid (LA) to a versatile platform chemical, γ-valerolactone (GVL), has received increasing attention because CTH can be implemented using alcohols as H-donors and non-noble metal catalysts. While conventional heating is commonly used for LA conversion via CTH, microwave irradiation (MWI) is employed for the first time to converting LA to GVL via CTH using UiO-66 as a non-noble metal catalyst. In comparison with the conventional heating, the MWI significantly accelerates LA conversion to GVL as the yields and selectivities are much higher than those obtained by conventional heating. This enhancement may be because Zr-O cluster of UiO-66 is more catalytic active owing to the quick and intensive heat and promoting effects from the ligand of UiO-66 under MWI. Additionally, the MWI is still able to enhance LA conversion substantially in less suitable alcohols for LA and enable the unfavorable UiO-66-NH2 to work and making the effective catalyst, such as UiO-66-SO3H, even more catalytically active. These features indicate that MWI is certainly a useful and effective approach for enhancing LA conversion via CTH. The findings of this study are also an important basis for developing highly effective LA conversion via CTH with MWI.
