Abstract

Reaction of [Ru^VI(N)(L¹)(MeOH)]⁺ (L ¹ = N,N′-bis(salicylidene)-o-cyclohexylenediamine dianion) with excess pyridine in CH₃CN produces [Ru^III(L ¹)(py)₂]⁺ and N₂. The proposed mechanism involves initial equilibrium formation of [Ru^VI(N)(L ¹)(py)]⁺, which undergoes rapid N⋯N coupling to produce [(py)(L¹)Ru^IIIN≡N-Ru^III(L ¹)(py)]²⁺; this is followed by pyridine substituion to give the final product. This ligand-induced N⋯N coupling of Ru ^VI≡N is utilized in the preparation of a series of new ruthenium(III) salen complexes, [Ru^III(L)(X)₂] ^± (L = salen ligand; X = H₂O, 1-Melm, py, Me ₂SO, PhNH₂, ^tBuNH₂, Cl^- or CN^-). The structures of [Ru^III(L¹)(NH ₂Ph)₂](PF₆) (6), K[Ru^III(L ¹)(CN)₂] (9), [Ru^III(L²)(NCCH ₃)₂][Au^I(CN)₂] (11) (L² = N,N′-bis(salicylidene)-o-phenylenediamine dianion) and [N ⁿBu₄][Ru^III(L³)Cl₂] (12) (L³ = N,N′-bis(salicylidene)ethylenediamine dianion) have been determined by X-ray crystallography. © 2008 American Chemical Society.
