Abstract
The complex alleged to have the stoicheiometry Ru(MeCN)2(PPh3)4 and to contain a π-bonded acetonitrile, produced by electrochemical reduction of RuCl2(PPh3)n(n= 3 or 4) in presence of acetonitrile, has been shown to be the hydrido ortho-metallated phosphine species RuH(MeCN)(C6H4PPh2)(PPh3)2; in the reduction of RuCl2(PPh3)3 in tetrahydrofuran–MeCN a red transient intermediate, believed on the basis of e.s.r. studies to be a d8 ruthenium(0) species, is formed.Keywords
