A highly practical procedure for the preparation of novel classes of chalcogen bearing diamines [H2N(CH2)n}E] and diols [HO(CH2)n}(2)E] (n = 2 or 3 and E = Se or Te) by the reaction of disodiumchalcogenide and haloalkylamines or haloalcohols is presented. (C) 2004 Elsevier Ltd. All rights reserved.
