摘要: Abstract The formato ligand is readily introduced into the 5-coordinate complexes MRCl(CO)(PPh 3 ) 2 (M = Ru or Os, R o -tolyl) giving 6-coordinate MR(η -O CH)(CO)(PPh . In presence of excess PPh thermal decarboxylation osmium complex leads to stable aryl, hydride, OsRH(CO)(PPh A similar reaction with RuR(η accompanied by reductive elimination RH and formation “Ru(CO)(PPh ” which as a solid ortho -metallated, i.e. exists Ru(C 6 H 4 P Ph )H(CO)(PPh Decarboxylation in bis(diphenylphosphino)ethane (dppe) give zerovalent Ru(CO)(dppe) undergoes most unusual formaldehyde forming Ru(CH )(η
