Highly effective synthesis of a cobalt(ii) metal-organic coordination polymer by using continuous flow chemistry.

The coordination polymer [Co2L4(H2O)2]·CH3CN·H2O (HL = (E)-2-[2-(4-chlorophenyl)vinyl]-8-hydroxyquinoline) has been achieved with 95% yield by using an Asia flow synthesis system (chip reactor). Compared with the conventional batch-type methods such as diffusion, reflux and solvothermal reactions, higher yielding reactions carried out in a flow reactor have demonstrated that this technique is a powerful strategy to obtain coordination compounds.
