The deviation from low catalyst for sour environment which does not possess separate metal hydrogenation functionThe hydrocarbon raw materials, the catalyst in order deviation from low to do the raw materials which especially possess the high sulfur and nitrogen level is offered. The deviation from ...
Fast and furious: Even without the assistance of an NH donor ligand, the Ru complex shown in the scheme is a remarkably active precatalyst for the transfer hydrogenation of ketones in basic iPrOH (R,R′=alkyl or aryl), providing near-quantitative yields within minutes and exhibiting ...
