Inorganics | Free Full-Text | Understanding Factors that Control the Structural (Dis)Assembly of Sulphur-Bridged Bimetallic Sit

Abstract Bimetallic structures of the general type [M 2 (µ-S) 2] are omnipresent in nature, for biological function [M 2 (µ-S) 2] sites interconvert between electronically distinct, but isostructural, forms. Different from structure-function relationships, the current ...

Rhodium(II)-Catalyzed 1,3-Dipolar Cycloaddition Reactio

tion. The earliest example of a rhodium(II)-catalyzed -diazo ketone decomposition to form a 1,3-dipole was described by Bien (Scheme 19.1) [20]. In this paper, the authors reported that the cyclopropanation gave 2 and 3 as the major products when palladium was used as the catalyst; however, rhodium catalysis provided cycloaddition adduct 5 as

Preparation and characterization of nitrogen-sulfur donor .

Tetradentate bis-aminoethanethiol ligands form 1:1 complexes with technetium of the general form: TcOXL. These complexes are also stable in solution and exchange very slowly with 1,2-ethanedithiol. The synthesis of the ligands and complexes are described and the implications of the results obtained on radiotracer development are discussed.
