The carbonyl(hydrido) complexes MHCl(CO)2 (4: M= Ru; 5: M= Os) react with aldoximes and ketoximes to give the octahedral hydrido(oxime)ruthenium and -osmium compounds MHCl(CO)2 (8-13) in high yields.Using MHCl(CO)(PiPr3)2 (6,7) as starting materials, the complexes MHCl(CO)(PiPr3)2 (14-16) are obtained.Reactions of 9 (M= Os; R= R'= CH3) illustrate that the oxime ligand in the hydrido(oxime) compounds is easily displaced by Lewis bases.Either from 4, 5 and Na in methanol or from 8-13 and NaH in THF the hydrido(oximato) complexes 20-25 in which the oximato ligand is coordinated via N and O, are formed almost quantitatively.CO opens the three-membered ring by cleavage of the M-N bond.Analogously, the alkenyl(oximato) compounds 28-30 are obtained from MCl(CO)2 (18: M= Os; 27: M= Ru) with Na.
