We describe the synthesis of ionic-liquid-supported 1,3-dimethylimidazolidin-2-one, together with the halogenation of alcohols in a reaction system in which this reagent is combined with oxalyl chloride. A new method was established that does not require additives such as bases, and which permits the ready isolation and purification of the product. Good conversions were obtained, and good reusability of the reagent was observed.

Page/Page column 12; 13; 14, (2016/08/17)
The present invention relates to a modified polymer obtained by grafting of a compound comprising at least one group Q and at least one group A, bonded together by at least, and preferably, one “spacer” group Sp in which: Q comprises a dipole containing at least, and preferably, one nitrogen atom, capable of being grafted onto the polymer chain by [1,3]-dipolar cycloaddition,A comprises an associative group comprising at least one nitrogen atom,Sp is an atom or a group of atoms forming a bond between Q and A.
