In this study, a Ru-immobilized bisphosphine-based porous organic polymer (Ru@PP-POP) was used as an efficient heterogeneous catalyst for the chemoselective hydrogenation of cinnamaldehyde to cinnamyl alcohol with high chemoselectivity (98%) and excellent recyclability. The catalyst showed a high turnover number (970) and a high turnover frequency (240h^-1), representing the best activity obtained using a phosphine-based heterogeneous Ru-catalyst in this transformation.
Selective hydrogenation of the carbonyl functional group of alpha,beta-unsaturated carbonyl compounds affords industrially important allylic alcohols. However, achieving the selective reduction of the carbonyl group in the presence of the activated olefinic group is challenging. Therefore, the development of a highly chemoselective, efficient, and recyclable catalyst for this transformation is greatly desirable from the industrial and environmental viewpoints. In this study, a Ru-immobilized bisphosphine-based porous organic polymer (Ru@PP-POP) was used as an efficient heterogeneous catalyst for chemoselective hydrogenation of cinnamaldehyde (CAL) to cinnamyl alcohol with high chemoselectivity (98%) and excellent recyclability. To the best of our knowledge, the catalyst, Ru@PP-POP showed a high turnover number (970) and a high turnover frequency (240h(1)) which is the best activity obtained using a phosphine based heterogeneous Ru-catalyst in this transformation.
