New routes to the preparation of [ru3(co)12], [h4ru4(co)12], [rucl2(pph3)3] and [rucl2(cod)]n from anglo platinum refinery
(Zimbabwe Journal of Science and Technology, 2013) Chiririwa, Haleden; Moss, John R.
New and improved routes for the preparation of ruthenium complexes are described. [Ru3(CO)12], [H4Ru4(CO)12], [RuCl2(PPh3)3] and [RuCl2(COD)]n have been prepared from [(NH4)2RuCl6] and [H2RuCl6]. Traditionally these ruthenium complexes have been prepared from commercially available RuCl3.3H2O, but here we describe their preparation from refinery materials.
