Versatility of Bidentate Aniline Derivatives as Ligands for Rhenium (V) and Technetium (V)

Versatility of V-Y Flap in Gluteal Area

BACKGROUND Lesions in perineal area are common. The usual treatment is coverage by skin graft and flaps which may be local, pedicled or free types. In this paper V-Y flaps were used to cover the defects. METHODS V-Y flaps were used in the gluteal area in 15 patients. Lesions were due to different causes. RESULTS Of 15 patients, 11 were males and 4 were females. Their ages ranged from 3...

Rhenium complexes of bidentate, bis-bidentate and tridentate N-heterocyclic carbene ligands.

A series of eight Rhenium(I)-N-heterocyclic carbene (NHC) complexes of the general form [ReCl(CO)3(C^C)] (where C^C is a bis(NHC) bidentate ligand), [ReCl(CO)3(C^C)]2 (where C^C is a bis-bidentate tetra-NHC ligand) and [Re(CO)3(C^N^C)](+)[X](-) (where C^N^C is a bis(NHC)-amine ligand and the counter ion X is either the ReO4(-) or PF6(-)) have been synthesised using a Ag2O transmetallation proto...

Unusual metalloporphyrin complexes of rhenium and technetium.

New hybrid bidentate ligands as precursors for smart catalysts.

1-Phosphanorbornadiene derivatives were grafted onto various periodically organized mesoporous powders, including a new zirconia/silica mixed oxide synthesized by aerosol techniques. After complexation with the [Rh(CO)2]+ fragment, these materials were revealed to be more active in olefin hydrogenation than their homogeneous counterparts. The reasons for this higher activity are discussed in th...
