Synthesis of a series of new platinum organometallic complexes derived from bidentate Schiff-base ligands and their catalytic activity in the hydrosilylation and dehydrosilylation of styrene.

The synthesis and properties of a novel class of platinum complexes containing Schiff bases as O,N-bidentate ligands is described as are the solution and solid state properties of the uncomplexed ligands. The platinum complexes were prepared from [PtBr2(COD)] (COD = 1,5-cyclooctadiene) and N-(2-hydroxy-1-naphthalidene)aniline derivatives in the presence of base (NaOBu(t)). Instead of a substitution reaction to afford cationic species, the addition of the Schiff base ligands results in both the formal loss of two equivalents of bromide and addition of hydroxide to the COD ligand of the complexes.

[Adrenal metastasis: survival following surgical resection].

Goal: This study aims to determine the post-surgical survival after resection of adrenal metastasis from extra-adrenal primary cancers.

Patients And Methods: A retrospective study of sixteen patients undergoing surgery for adrenal metastasis between 1995 and 2005 analyzed age, type of primary cancer, interval to detection of adrenal metastasis, type of surgery performed, and survival (Kaplan-Meier curve).

Results: The study included 10 men and 6 women with a mean age of 55.
