Chloro(dimethylformamide-κ<i>O</i>)(hydridotripyrazolylborato)(tripyrrol-1-ylphosphine-κ<i>P</i>)ruthenium(II)

The air‐sensitive DMF‐containing intermediate [RuTp(PR3)(Cl)(DMF)] is formed by refluxing a DMF solution of [RuTp(COD)Cl] (1) in the presence of at least 1 equiv. of PR3 (PR3 = PPh3, PPh2iPr, PiPr3, and PCy3). On exposure to air in the presence of CCl4, this complex is readily converted into the respective RuIII complexes [RuTp(PR3)Cl2] (2a–d). These compounds are air‐stable, readily accessible, permit easy variations as far as the electronic and steric properties of the PR3 co‐ligands are concerned, and are reducible to a variety of RuIITp complexes. Treatment of 2 with NaBH4 affords dihydrogen compounds of the type [RuTp(PR3)(H)(η2‐H2)]. Reduction of 2 can also be accomplished with Zn in the presence of CH3CN and pyridine, which affords the diamagnetic RuII compounds [RuTp(PR3)(CH3CN)2]+ (4a–c) and [RuTp(PR3)(py)Cl] (5). X‐ray structures of representative complexes are presented. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
