Abstract: An improved method for the preparation of title compounds was reported. Refluxing lchloro-2-(3,4-dichlorophenoxy)ethane 3a with sodium iodide in 1-butanol gave 1-iodo-2-(3,4-dichlorophenoxy)ethane 4a in yield of 87%. Reacting 4a with diethylamine in acetone afforded 2-(3,4-dichlorophenoxy) ethyldiethylamine la in good yield (88%).The analogues 1b,2a and 2b were prepared similarly.

Key words: dichlorophenoxyethyldiethylamine, plant growth regulator, synthesis
