Photocatalytic treatment of organoselenium in synthetic mine-impacted effluents
Water Science and Technology, 2023 Biological selenium reduction processes are commonly employed as the best available technology (BAT) for selenium removal; however, as a by-product they produce trace amounts of organoselenium compounds with orders of magnitude greater bioaccumulation ...

Organoselenium chemistry [PDF]
, 2018 Organoselenium chemistry has been established as a valuable research area in synthetic and medicinal chemistry. After the discovery of the selenoxide elimination reaction in the early 1970s, organoselenium reagents achieved great success in organic synthesis including asymmetric synthesis. More commonly, synthetic transformations such as selenenylation,
