Ethyl potassium maleate

The methyl esters of dicarboxylic acids88 give no dicarboxylic products only mono-carboxylic acid derivatives are formed. Dimethyl succinate, dimethyl maleate and dimethyl acetylenedicarboxylate over potassium tetrafluorocobaltate(III) at 270-350"C all give mixtures of (crude products are converted into ethyl esters) ethyl pentafluoropropanoate and ethyl...

On the other hand, chemicals might be chosen as agents for generation of active centers in the polymeric backbone and grafting of monomer in the vapor phase. Ammonium persulfate and styrene (189), acrylic acid (190), butyl acrylate (191), potassium persulfate and n-butyl maleate or 2-ethyl hexyl acrylate (55,134) and ammonium ceric nitrate and methacrylic add (192) are examples of this method. Benzoyl peroxide deposited on polycaprolactam fibers initiates the grafting of styrene in vapor phase (193). [Pg.106]

This centrally acting analgesic agent242, ethyl 2-amino 6 [(4-fluorophenyl)methyl] amino -3-pyridinyl-2,6-14C carbamate maleate, 238, has been 14C-labelled243 in nine steps starting with potassium cyanide[14C] and 1,3-dibromopropane (equation 100). [Pg.1196]
