Synthesis of unnatural selenocystines and beta-aminodiselenides via regioselective ring-opening of sulfamidates using a sequential, one-pot, multistep strategy.

J. Org. Chem. 75(9) , 2910-21, (2010)

A variety of N-alkyl-beta-aminodiselenides have been synthesized in high yield from sulfamidates under mild reaction conditions using potassium selenocyanate and benzyltriethylammonium tetrathiomolybd...

Nutritional availability and chronic toxicity of selenocyanate in the rat.

J. Nutr. 118(6) , 718-22, (1988)

To evaluate nutritional availability and chronic toxicity of KSeCN, female postweanling rats were fed casein-based diets plus 0.1, 0.5, 2.5, 5 and 10 mg Se/kg as KSeCN for 6 wk, or 0.1, 0.5 and 10 mg ...

Selenium assimilation and volatilization from selenocyanate-treated Indian mustard and muskgrass.

Plant Physiol. 128(2) , 625-33, (2002)

Selenocyanate (SeCN(-)) is a major contaminant in the effluents from some oil refineries, power plants, and in mine drainage water. In this study, we determined the potential of Indian mustard (Brassi...
