环状二酯，特别是生物质衍生的乙交酯和丙交酯，到相应的1，2-二醇的前所未有的均相氢化由Ru（II）PNN（1）和Ru（II）CNN（2）钳形络合物在温和的氢压和（在1的情况下）中性条件下催化。当使用手性二酯时，没有观察到外消旋化。
The unprecedented homogeneous hydrogenation of cyclic di-esters, in particular biomass-derived glycolide and lactide, to the corresponding 1,2-diols is catalyzed by Ru(II) PNN (1) and Ru(II) CNN (2) pincer complexes under mild hydrogen pressure and (in the case of 1) neutral conditions. No racemization was observed when a chiral di-ester was used.
