Ionic [Ru] complex with recyclability by electro-adsorption for efficient catalytic transfer hydrogenation of aryl ketones

Abstract

The effi cient reuse of homogeneous catalyst is important. P-NMR), element analysis (EA), and high resolution mass spectrometry (HR-MS). The complex was used as a catalyst for the hydrogen transfer reduction of carbonyl for the fi rst time, presenting an excellent catalytic performance of 89%-98% conversion of acetophenone and its derivatives. The catalyst may be effi ciently reused by the electro-adsorption of 10 times to one catalyst recovery. The cation [Ru] complex presented advantages of both homogeneous and heterogeneous catalysts.
