Synthesis and Reactivity of Tris(7-azaindolyl)boratoruthenium Complex. Comparison with Poly(methimazolyl)borate Analogue

Abstract

Abstract A reaction of [Cp*RuCl]4 (Cp* = η5-C5(CH3)5) with K[HB(aza)3] (aza = 7-azaindolyl) afforded the first organometallic HB(aza)3− complex [Cp*Ru{HB(aza)3-κ3H,N,N′}], which lost one of the aza-units coordination upon treatment with carbon monoxide to give the mono(carbonyl) complex [Cp*Ru{HB(aza)3-κ2H,N}(CO)]. The crystal structures of these complexes have been determined by X-ray crystallography.
