Synthesis, crystal structures, and properties of the copper(I) halide coordination polymers ∞2[CuX(μ-2-chloropyrazine-N,N′)] (X = Cl, Br), ∞1[CuI(2-chloropyrazine-N)], and [Cu2I2(2-chloropyrazine)]

The new copper coordination polymers ∞2[CuX(μ-2-chloropyrazine-N,N′)] (X = Cl (I), Br (II), ∞1[CuI(2-chloropyrazine-N)] (III) and [Cu2I2(2-chloropyrazine)] (IV) has been prepared by the reaction of the copper(I) halides with 2-chloropyrazine at room-temperature or under hydrothermal conditions. The crystal structures of the 1:1 compounds I and II consist of zig-zag CuX single chains running parallel to the crystallographic a-axis which are linked by the 2-chloropyrazine spacer molecules to sheets parallel to (010). For the iodine compound III a one-dimensional structure is Found which consists of CuX double chains running parallel to the crystallographic a-axis. The thermic properties of all compounds were investigated in different gas atmospheres using simultaneously differential thermal analysis and thermogravimetry (DTA-TG) as well as temperature resolved X-ray powder diffraction. On heating, tire 1:1 compounds I and II decompose directly to the corresponding copper(I) Halides, whereas the thermal decomposition of III occcur via IV as an intermediate.

The chlorination of hydroxy aza-arenes with bis(trichloromethyl) carbonate (BTC) and SOCl2 has been effectively performed by refluxing with 5 wt % 4-dimethylaminopyridine (DMAP) as a catalyst. Various substrates are chlorinated with high yields. The obtained chlorinated aza-arenes can be used directly with simple workup for succedent one-pot synthesis on a large scale.
