Abstract

The regiochemistry was investigated for the reaction of 2‐chloromethyl‐4,5‐dichloropyridazin‐3(2__H__)‐one (1**)** with some phenols 2 in the presence of a base in organic solvents. Seven diphenoxy derivatives 5 were synthesized selectively from 1 and phenols 2 under two optimized conditions. The product distributions of these reactions are dependent on the base, the solvent, and/or the substitutes of phenols. J. Heterocyclic Chem., (2009).

## 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
