It has been also found that hydroperoxide dehydrase from flax seeds converts 8-hydroxy-15 S -hydroperoxy derivatives of arachidonic and eicosapentaenoic acids into a-ketols and prostaglandin A3 analogues [2]. These data allow us to hypothesize formation of ketols of 9-hydroxy derivative of a-...

Perfluoropropene reacts with triethylammonium azide in sym-tetrachloroethane or sodium azide in dimethylformamide at low temperatures to give perfluoropropenyl azide, which decomposes at 20掳 into nitrogen and perfluoro-(2-methyl-2H-azirine). Hydrolysis of the azirine provides trifluoropyruvic acid. ...
