Electrochemical generation and catalytic use of selenium electrophiles

The generation and use of selenium electrophiles in ­catalytic, electrochemically driven selenenylation-elimination sequences is described

Catalytic use of selenium electrophiles in cyclizations

A new and convenient one-pot method for a catalytic addition-elimination reaction using selenium electrophiles has been developed. In the presence of 5 mol % diphenyl diselenide, [bis(trifluoroacetoxy)iodo]benzene in acetonitrile converted a range of (E)-3-butenoic acids into the corresponding butenolides in good yields

Catalytic addition-elimination reactions towards butenolides

A wide range of selenium-containing reagents are known to undergo addition – elimination reactions under different reaction conditions. We report on selenium electrophiles, which are regenerated under the reaction conditions employed, and therefore only catalytic amounts of these reagents are necessary

Innovation of Toilet Septic Method by Atmospheric Plasma

After the east Japan earthquake, the suffered people has a much troubles in their living lives, especially in their meals, sleeps and toilets. Normal people in the world does not pay attention to the excreta and filthy water [1]. However, now in the removal of NH3 in toilet septic tank, a bacteria method has been applied, which produces a much sewage sludge in the excreta. A much expenses and human loads will need to take out the slime sludge. In order to solve it, we will apply the interaction between a liquid and an atmospheric plasma [2] and the ammonium stripping method by chemical reactions. The out line is presented here
