Description

Application

Ring opening of aziridines leading to sulfides and disulfides.

This classic building block for transition metal sulfide cluster compounds was recently used in a low-temperature, solid state synthesis of a new series of heterometallic sulfide clusters stabilized with dppm [bis(diphenylphosphino)methane] ligands.

Biochem/physiol Actions

Acts as a chelator in vivo to reduce copper levels. Tetrathiomolybdate interferes with angiogenesis and reduces tumor growth. Its mechanism may involve inhibition of NF-κB and downstream cytokines.
