Solid state structure and solution behaviour of organoselenium(ii) compounds containing 2-{E(CH2CH2)2NCH2}C6H4 groups (E = O, NMe)†
Abstract
Cleavage of the Se–Se bond in [2-{O(CH2CH2)2NCH2}C6H4]2Se2 (1) and [2-{MeN(CH2CH2)2NCH2}C6H4]2Se2 (2) by treatment with SO2Cl2, bromine or iodine (1 : 1 molar ratio) yielded [2-{O(CH2CH2)2NCH2}C6H4]SeX [X = Cl (3), Br (4), I (5)] and [2-{MeN(CH2CH2)2NCH2}C6H4]SeI (6). The compounds were characterized in solution by
