Stepwise ligand transformations through [2+2] photodimerization and hydrothermal in situ oxidation reactions

The SCSC transformation of a 1D polymer [Cd(1,3-bdc)(4-spy)(2)](n) produced a 2D polymer [Cd(1,3-bdc)(4-spy)(HT-ppcb)(0.5)](n) through the [2+2] photodimerization reaction. Hydrothermal reactions of HT-ppcb with CdCl2, 1,3-H(2)bdc and H2O2 afforded another 2D polymer {[Cd(H2O)(1,3-bdc)(bpbpf)]center dot H2O}(n) in which HT-ppcb underwent in situ oxidation to form a unique furan-based ligand bpbpf.
