The photocoupling reactions of 1,3-dimethyl-5-iodouracil with benzene and substituted benzenes were studied. The structures of the 13 new compounds obtained were determine by IR, NMR, MS or elemental anal. The substituent effects on the reactions and the mass spectrum of the products are discussed. The reactions were accelerated by a triplet sensitizer.

Key words: PHOTOCHEMICAL REACTION, REACTION MECHANISM, DIMETHYL GROUP, MASS SPECTROGRAPHY, BENZENE P, ORGANOIODINE COMPOUNDS, STERIC EFFECT, ELECTRONIC EFFECT, SUBSTITUENT EFFECT, CRACKING REACTION
