The sodium borohydride reduction of [Ru(MeCN)3(triars)](CF3SO3)2 (triars = MeC(CH2AsPh2)3) in methanol yields the bis(amine) hydride [RuH(NH2CH2Me)2(triars)](CF3SO 3). The amine and methylene protons are inequivalent on the NMR time scale up to +80°C. Deuterium substitution studies support the intermediacy of a metal-imine complex in the reduction. By contrast, reaction of NaBH4 and [Ru(MeCN)3(triphos)](CF3SO3)2 (triphos = MeC(CH2PPh2)3) gives the hydride borohydride complex [RuH(BH4)(triphos)]. NMR and GC measurements prove that MeCN is not reduced to amine in this case. The difference in reactivity is attributed to the difference in trans effects of the phosphorus and arsenic donors.
