C-H activation of a 2,2[prime or minute]-bipyridine ligand within (mono)pentamethylcyclopentadienyl lutetium complexes.
We report the activation of a 2,2'-bipyridine ligand within a class of (mono)cyclopentadienyl lanthanide complexes when reacted with carbon monoxide.

Unusual alkyl group activation and cationic complex formation from a novel lutetium dialkyl complex supported by a tridentate monoanionic ligand.
We report herein the synthesis and characterization of a lutetium dialkyl complex supported by a multidentate, anilido-pyridine-imine ligand and its subsequent transformation into an unprecedented cationic monoalkyl derivative.

Structure and reactivity studies of the first tungsten cyanoalkylidene complex.
Alkylidene complex W(CHCMe2Ph)(NAr)[OCMe(CF3)2]2 (Ar = 2, 6 diisopropylphenyl) (4) reacts with one equivalent of acrylonitrile in methylene chloride to afford the tetrameric, cyanoalkylidene complex [W(CHCN)(NAr)[OCMe(CF3)2]2]4 (5) which reacts with excess acetonitrile to give the tetrameric complex [W(N(H)C(CH3)C(CN)C(CH3)N)(NAr)[OCMe(CF3)2]2]4 (6).

The synthesis and reactivity of a molybdenum (IV) stretched-dihydrogen complex.
Reaction of [Mo(NPh)(PMe3)3(o-(Me3SiN)2C6H4)] (1) with molecular hydrogen (ca. 1 atm) at -10 degrees C in toluene-d8 results in the formation of dihydrogen complex [Mo(NPh)(PMe3)2(H2)(o-(Me3SiN)2C6H4)] (2) by 1H and 31P NMR spectroscopy. In solution at -50 degrees C 1 and 2 are present in a 1:3 ratio, respectively. The nature of dihydrogen ligand bonding in 2 was probed by T1 analysis and analysis of the JH-D coupling constant in the deuterium hydride isotopomer of 2 giving H-H distances of 1.18 A and 1.17 A, respectively. When allowed to warm to 30 degrees C, 2 reacts affording [Mo(NPh)(PMe3)3(o-(Me3SiN)(NH)C6H4)] (3) over a 1 h period. The X-ray structures of 1 and 3 are reported.
