## Abstract 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‐hydroxyphen
## Abstract The reactions of 3‐acetoacetyl‐7‐methyl‐2__H__,5__H__‐pyrano[4,3‐__b__]pyran‐2,5‐dione with aromatic amines afforded 3‐(arylaminomethylene)‐6‐methylpyran‐2,4‐dione. Our results allowed the correction of the structures reported in the literature for the products of these reactions.
