1,2,4‐Triazin‐5(2 H )‐ones 1 react as well with phenols, resorinol and its dimethyl ethers, as with dimethyland diethylaniline, yielding 6‐aryl‐1,6‐didydro‐1,2,4‐triazin‐5(2 H )‐ones 2, 4–8, 12–15. Oxidation of the 1,6‐dihydroadducts 2a,b gives the corresponding 3‐aryl‐6‐hydroxyphenyl‐1,2,4‐triazin‐5(2 H )‐ones 3a,b. Rection of 1,2,4‐triazinones 1 with 2‐naphthylamine leads to destruction of the 1,2,4‐triazine ring yielding benzo[e]indole‐2,3‐dione 19.
