A SIMPLE SYNTHESIS OF 2,4-DIARYL-1,3,5-TRIAZINES

Arylamidines 2 react with -methoxymethylen-2,2-dimethyl-1,3-dioxan-4,6 -dione 5 to give 2,4-diaryl-1,3,5-triazines in moderate to good yields . 5 can be comprehended as a formic acid derivative which transfers a C-1-building block. Other formic acid derivatives give only poor to mo derate yields of triazines by treatment with amidines. The synthetic m ethod is applicable to aromatic amidines.
