Abstract

(PMe₃)₄Ru(H)OAc has been prepared from (PPh₃)₃Ru(H)OAc via phosphine exchange followed by solvent partitioning between acetonitrile and pentane. Complexes of the type (PMe₃)₄Ru(H)R (R = Et, ⁿPr, ⁿBu, ⁱBu, H) have been synthesized through reaction with the corresponding Grignard reagents, RMgCl, and were found to be moderately stable provided the alkyl group is primary. Treatment with bulkier alkylmagnesium chlorides led instead to the dihydrido complex (PMe₃)₄RuH₂. In some cases, the reaction was complicated by transfer of halide from the Grignard reagent to form, for example, (PMe₃)₄Ru(H)Cl.
