| Abstract: | ![]()
When heated with Group V and Group VI elements, the phenylenemercurials (C6H4Hg)3, (C6F4Hg)3 and (C6Cl4Hg)3 form heterocycles of formulae (M2(C6X4)3 and M′2(C6X4)2 where M = As, Sb, Bi and M′ = S, Se, Te. The compounds Te2(C6Cl4)2 and M2(C6Cl4)3 (M = As, Sb, Bi) were also obtained by heating the elements with 1,2-I2C6Cl4, which was prepared by mercuration of 1,2-H2C6Cl4 followed by iododemercuration. Octachlorothianthrene has been obtained by heating sulphur with Te2(C6Cl4)2, C6Cl6 or C6Cl5I, and from the reaction between 1,2-H2C6Cl4, AlCl3, and S2Cl2. |
