Palladium-catalyzed bond-forming reactions, such as the Suzuki–Miyaura and Mizoroki–Heck reactions, are some of the most broadly utilized reactions within the chemical industry. These reactions frequently employ hazardous solvents; however, to adhere to increasing sustainability pressures and restrictions regarding the use of such solvents, alternatives are highly sought after. Here we demonstrate the utility of dimethyl isosorbide (DMI) as a bio-derived solvent in several benchmark Pd-catalyzed reactions: Suzuki–Miyaura (13 examples, 62–100% yield), Mizoroki–Heck (13 examples, 47–91% yield), and Sonogashira (12 examples, 65–98% yield).
钯催化的键合反应,如Suzuki–Miyaura和Mizoroki–Heck反应,在化工行业中被广泛使用。这些反应通常使用危险溶剂;然而,为了遵守日益增加的可持续性压力和有关使用此类溶剂的限制,人们迫切寻求替代方案。在这里,我们展示了二甲基异山梨醇醚(DMI)作为生物衍生溶剂在几种基准Pd催化反应中的实用性:Suzuki–Miyaura(13个示例,收率62–100%),Mizoroki–Heck(13个示例,收率47–91%)和Sonogashira(12个示例,收率65–98%)。
