With [(p-cym)RuCl2]2 (1) as the starting material, the halfsandwich-type complexes [(p-cym)RuCl2(SbiPr3)] (2) and [(p-cym)RuCl(SbiPr3)2]PF6 (3) were prepared. Treatment of RuCl3·3H2O in ethanol gave, after addition of SbiPr3, the monocarbonyl compound [RuCl2(CO)(SbiPr3)3] (4), which reacted with CO by ligand exchange to yield [RuCl2(CO)2(SbiPr3)2] (5). The reaction of RuCl3·3H2O in ethanol, in the presence of Na2CO3, afforded the chloro(hydrido) derivative [RuHCl(CO)(SbiPr3)3] (6). Analogously, using OsCl3·3H2O as the starting material, the chloro(hydrido)osmium complex [OsHCl(CO)(SbiPr3)3] (8) was prepared. The reactions of 8 with C2H4, C2(CO2Me)2 and NaBH4 led to the formation of compounds 9, 10 and 11, which all contain the Os(SbiPr3)2 unit as a building block. While treatment of 6 with C2(CO2Me)2 yielded the substitution product [RuHCl(CO)(MeO2CCCCO2Me)(SbiPr3)2] (14), the corresponding reaction of 6 with HCCPh and HCCCPh2OH afforded the alkynyl and allenylidene ruthenium(II) complexes [RuCl(CCPh)(CO)(SbiPr3)3] (16) and [RuCl2(=C=C=CPh2)(CO)(SbiPr3)2] (17), respectively. Compounds 4 and 17 were characterized by X-ray crystal structure analysis.
