Selenium Stabilized Carbenium Ions on Organic Synthesis
Organoselenium compounds have been known for a long time as versatile reagents in organic chemistry. In the last years there has been a considerable development of selenium-based methods for organic synthesis. Many of these methods are currrently been used as standard procedures to introduce new functional groups under mild conditions. From the several areas of interest in organoselenium chemis...
متن کاملSelenium: more than just a micronutrient mineral.
Selenium is a micronutrient mineral found mainly in soils. Studies on selenium have increased rapidly worldwide especially after it has been shown to reduce the risk of certain types of cancer in humans and animals. The exact mechanism of action on how selenium inhibits diseases, in particular cancer, is still unknown. To date, the use of selenium in preventing or treating diseases is limited. ...
متن کاملComparing ORGANIC SELENIUM sources
wide range of products is available; from inorganic, sodium selenite or selenate coated or not, even nanoparticles to organic forms such as selenized yeasts, chelates of selenium methionine (SeMet), pure forms of SeMet or hydroxy-selenomethionine, and some complexes sources of Se based on mixing mineral Se with glycinates, proteinates, etc. It has been confirmed that, comparing with mineral sel...
متن کاملMicronutrient Deficiency Syndrome: Zinc, Copper and Selenium
Nutrients are defined as not only having nutritive values of participating in the metabolism and building the structures of cells but also being safe for human body. Nutrients are divided into two types, macronutrient and micronutrient, according to the proportion of the human body. Commonly, micronutrients include trace elements (trace mineral) and vitamins (complex organic molecules). It is d...
متن کاملSulfur- and selenium-based linkers in polymer-supported organic synthesis
The use of sulfurand selenium-based linkers in polymer-supported organic synthesis (PSOS) is reviewed. The literature describing the application of sulfur-based linkers in the PSOS of small molecules and combinatorial library preparation from 2000 to the present is summarized. The development and use of selenium-based linkers in PSOS, highlighting the work of the Nicolaou and Huang groups, is a...
