摘要： A cross-linked polymer-supported 4-(N-benzyl-N-methylamino) pyridine material and process for its preparation in high yield and having effective physical and catalytic properties. The polymer-supported catalyst is characterized by the suspension copolymerization of an organic phase containing the corresponding vinyl-substituted pyridine monomer, a styrene monomer, and a suitable cross-linking agent and free radical-generating catalyst in the presence of an aqueous phase containing a cellulose ether derivative as the stabilizing agent. A purified acid salt of the vinyl-substituted pyridine monomer useful in polymerizations and stable for storage as either a solid or an aqueous solution.

摘要： Imines are synthesized by the hydrogenation of pyridinecarbonitriles with amines in the presence of a rhodium-loaded catalyst. The resulting imines are stable and may be transiminated and then hydrogenated to form selected secondary amine products or may be hydrolyzed to aldehydes.Further, a very useful class of unsymmetrical secondary amines represented by the formula RCH.sub.2 NHAr (in which R is not aliphatic and Ar is aromatic and not attached to R), which has heretofore been accessible only with some difficulty, can be synthesized by processes herein disclosed utilizing the reductive intermolecular coupling of nitriles and primary aromatic amines.
