摘要：

A new convenient synthesis and the crystallographic characterization of [Ir(acac)(coe)(2)] (2, acac = acetylacetonato; coe = cis-cyclooctene) are described. The title compound crystallized from THF/ethanol in two modifications (monoclinic P2(1)/c, 2a, and triclinic P (1) over bar, 2b). Complex 2 represents an efficient starting material in the synthesis of mononuclear iridium(III) complexes containing cyclometalated 2-phenylpyridinato ligands using oxidative addition reactions of the corresponding ligands towards 2. Thus [Ir(acac)(ppy)(2)] (3, ppy = 2-phenylpyridinato) and [Ir(ppy)(3)] (4) (mer, 4a; fac, 4b) were prepared in excellent yields and short reaction times in a kind of one-pot procedure starting from [{Ir(mu-Cl)(coe)(2)}(2)] (1). Furthermore a convenient synthesis of [{Ir(mu-Cl)(ppy)(2)}(2)] (5) from 1 and Hppy is described. (C) 2010 Elsevier B.V. All rights reserved.
