    摘要: The present invention relates to a method of creating a carbon-heteroatom bond, and preferably a carbon-nitrogen bond, by reacting a leaving group-bearing unsaturated compound and a nucleophilic compound. In particular, the invention relates to the creation of a carbon-nitrogen bond, using a method involving the arylation of nitrogenous organic derivatives; the inventive method consists in creating a carbon-heteroatom bond by reacting a leaving group-bearing unsaturated compound and a nucleophilic compound introducing a heteroatom which can be substituted for the leaving group, thereby creating a carbon-heteroatom bond, in the presence of a palladium-based catalyst, optionally a ligand. The invention is characterized in that the reaction takes place in the presence of an effective quantity of a metal hydroxide or ammonium hydroxide which is associated with an alcohol-type solvent.

    摘要: A method has been developed for making regenerated cellulose yarn. The method includes the steps of spinning a solution derived from cellulose or a cellulose derivative in a molten state through at least one extrusion die, then regenerating the cellulose by treating the resulting yarn, wherein a silylated cellulose derivative is prepared by reaction with a silylating agent; the silylated cellulose is extracted from the synthesis reaction medium; then spun through at least an extrusion die; and the resultant yarn treated with a desilylation agent to regenerate the cellulose and a siloxane. The resulting cellulose yarns or fibers may be used for making woven or knitted textile surfaces or non-woven surfaces. Said yarns or fibers are also useful as reinforcing fibers in elastomeric materials and more particularly, in tires.
