• Microwave-assisted synthesis of the (E)-α-methylalkenoate framework from multifunctionalized allylic phosphonium salts

  日期：——

  A convenient and general microwave-assisted method for the synthesis of stereochemically defined α-methylalkenoic acids and esters from allylic phosphonium salts in a basic aqueous medium is described. A selective preparation of acids or esters was dependent on the base (NaOH or NaHCO3) employed in the reaction and could be achieved with good to excellent yields under mild conditions in the absence

  Flucculating agents for the selective flocculation of ultra­fine granulometry titanium and iron ores suspended in water, said agents being made up of polymeric or copolymeric compounds contain­ing as the monomeric units and monomers of formula I where R¹ and R², which can be the same or different, represent a -O-CHR⁵-O-bridge, or two hydroxyl groups which can also be in the form of their ether or ester derivatives, and in which formula one of the symbols R³, R⁴ or R⁵ corresponds to an atomic group contain­ing, at a position variously spaced from the substitution site, a polymerizable system which is preferably an olefinic system activated with respect to polymerization reactions, whereas the other symbols, which can be the same or different, can be hydrogen atoms or alkyl, aryl, hydroxyl, alkoxyl, hydroxyalkyl, alkoxyalkyl, haloalkyl, carbonyl, carboxyl, ester, amido, nitrilo, or sulfonic groups, or halogen atoms or nitro groups. The copolymerizable comonomers which can be copolymerized with said monomers of formula I are made up of olefinic compounds which are active towards polymerization reactions and contain groups whose hydrophilic character changes with the pH values.
