26-ETHYLIDENENITRILOPHENYLPYRIDINE, PRODUCTION THEREOF AND METAL SALT COMPLEX

摘要

NEW MATERIAL:2,6-Ethylidenenitrophenylpyridine expressed by formula I. USE:Capable of forming a metal complex expressed by formula II (X- is counter anion; M is bi- or trivalent metal) which is a high-spin complex, having paramagnetism and useful as catalytic, magnetic materials, etc. PREPARATION:One mol 2,6-diacetylpyridine and aniline in an amount of 2mol or a little larger than that are subjected to condensing reaction in the presence of a cresol catalyst, such as m-cresol, in an amount of about 2-5mol% based on 1mol 2,6-diacetylpyridine in a solvent, such as a mixed solvent of chloroform/ trichloroethane, while being heated and refluxed to afford the compound expressed by formula I.
