In this study, a commercially available homogeneous pincer-type complex, Ru-Macho, was directly heterogenized via the Lewis acid-catalyzed Friedel-Crafts reaction using dichloromethane as the cross-linker to obtain a heterogeneous, pincer-type Ru porous organometallic polymer (Ru-Macho-POMP) with a high surface area. Notably, Ru-Macho-POMP was demonstrated to be an efficient heterogeneous catalyst for the chemoselective hydrogenation of α,β-unsaturated carbonyl compounds to their corresponding allylic alcohols using cinnamaldehyde as a model compound. The Ru-Macho-POMP catalyst showed a high turnover frequency (TOF = 920 h) and a high turnover number (TON = 2750), with high chemoselectivity (99%) and recyclability during the selective hydrogenation of α,β-unsaturated carbonyl compounds.
在本研究中，一种市售的均相钳型配合物Ru-Macho通过以二氯甲烷为交联剂的路易斯酸催化傅克反应直接进行多相化，以获得具有高比表面积的多相钳型钌多孔有机金属聚合物（Ru-Macho-POMP）。值得注意的是，以肉桂醛为模型化合物，Ru-Macho-POMP被证明是一种高效的多相催化剂，可将α,β-不饱和羰基化合物化学选择性氢化为相应的烯丙醇。Ru-Macho-POMP催化剂在α,β-不饱和羰基化合物的选择性氢化过程中表现出高周转频率（TOF = 920 h⁻¹）和高周转数（TON = 2750），具有高化学选择性（99%）和可回收性。
