NEW METHOD FOR OBTAINING 8-PYRIDINIOTHEOPHYLLINATES
A new method for the synthesis of 8-pyridiniotheophyllinates by the action of pyridine or alkylpyridines on theophylline or 8-bromotheophylline in the presence of oxidizing agents was developed.The oxidation of 8-bromotheophylline gives the best results.This method was used to obtain 8-(2-methylpyridinio)theophyllinate, which could not be synthesized previously.

BROMO- AND IODODEMERCURATION OF 8-TRIFLUOROACETOXYMERCURI DERIVATIVES OF THEOPHYLLINE AND THEOBROMINE
Direct C-mercuration in the 8 position of N-acyl derivatives of theophylline and theobromine with mercury(II) trifluoroacetate in a mixture of anhydrous trifluoroacetic acid and trifluoroacetic anhydride is described. 8-Bromo and, respectively, 8-iodo derivatives of both dimethylxanthines were obtained in high yields from 8-trifluoroacetoxymercuri derivatives by the action of an aqueous solution of potassium tribromide or a solution of iodine in acetonitrile.
