METHOD OF SYNTHESIS OF SUBSTITUTED 1,10-PHENANTHROLINES

摘要

FIELD: organic chemistry. SUBSTANCE: product: new substituted 1,10-phenanthrolines of the general formulawhere: R=CH; i-CH; CH; R=CH- Ph; CH; i-CH; R; CH; i-CH; CH; R= CH; i-CH; CH. Method of synthesis involves interaction of o-phenylenediamine or 8-aminoquinoline with aliphatic or aromatic aldehydes or their mixture at molar ratio = 1:(2-4), at 140-160 C for 6-8 h in the presence of catalyst containing praseodymium trichloride, organophosphorus compound (PR) and dimethylformamide at mole ratio = (0.5-1.5):(2-4):(4-15). The yield of the end products is 50-80%. Synthesized compounds can be used in analytical chemistry and as semiproducts for synthesis of compounds showing pharmacological and pesticide activity. EFFECT: improved method of synthesis.
