Stepwise Sulfite Reduction on a Dinuclear Ruthenium Complex Leading to Hydrogen Sulfide

A research group led by Associate Professor Yasuhiro Arikawa and Motoki Yamada, a fourth-year student in the Department of Advanced Technology and Science for Sustainable Development at the Graduate School of Engineering, Nagasaki University, has successfully achieved the reductive conversion of sulfite on transition-metal-based complexes, leading to hydrogen sulfide.

Sulfur is a vital element that is ubiquitous across all ecosystems.  Sulfur can adopt various oxidation states in the global sulfur cycle, where sulfite reduction to hydrogen sulfide is the pivotal point of the biogeochemical sulfur cycle.  Recently, the significance of the sulfite reduction has been receiving increasing attention.  Dr. Yasuhiro Arikawa and his research group carried out the detailed research into the reductive conversion of sulfite using transition-metal-based complexes, leading to the achievement of the reductive conversion of sulfite. 

The research results were published in the Journal of the  American Chemical Society, a top journal in the field of chemistry, and were selected for the Supplementary Journal Cover.
