Reaction of the Schiff base ligand 1, prepared by the condensation of 2-chlorobenzaldehyde and N,N-dimethylethylenediamine with (η6-C6H5CH3)Mo(CO)3 2 resulted in the formation of the seven-coordinate molybdenum(II) metallacycle, 3, by oxidative addi

This work describes the synthesis, structures, and reactivity studies of a series of novel η2-nitrile and η2-alkyne complexes in which the sidebound nitrile and alkyne ligands serve as four-electron donor ligands. In these tungsten(II) carbonyl flu

This report describes a novel migratory insertion reaction which leads to the formation of highly fluorinated η2-vinyl complexes at a tungsten(II) metal center. Insight into the nature of this transformation was obtained by isolation and crystallogr

Two methods are described to derivatize silica with tethered tungsten(II) complexes. One method constructs the desired aryl halide ligand on the silica surface followed by oxidative addition using a source of ‘W(CO)3’. The second method involves

The reactions of a series of Schiff base ligands (1–4) prepared by condensation of pyridine-2-carboxaldehyde and 2-X-anilines (X = F, Cl, Br, OMe) with W(CO)3(RCN)3 results in the formation of deeply coloured complexes W(CO)3(1–4)(NCR) which read

The first examples of chelate assisted insertion of a transition metal centre into a C–F bond of mono- and di-fluoro substituted aromatic rings resulting in chelate stabilized aryl fluoride oxidative addition complexes are reported.
