Koehne, Ingo published the artcileSynthesis of Geminal Bis- and Tetrakisphosphonate Ester Derivatives and Their Coordination Behavior Towards Ca(II) Ions, Synthetic Route of 21101-63-3, the publication is European Journal of Inorganic Chemistry (2022), 2022(17), e202200194, database is CAplus.
The preparation and thorough characterization of a variety of (arylmethylene)phosphonate ester derivatives (S1-S7) as well as derived geminal bisphosphonate (BP) ester ligands (L1-L7) is presented. Subsequent complexation reactions of CaCl2 with selected BPs (L1-L3) and a known aliphatic tetrakisphosphonate ester (L8) yield the resp. Ca(II) coordination compounds [Ca(H2O)2(L1-L3)2]Cl2 (C1-C3) and [Ca(L8)Cl2]n (C4) for potential future application as multi-delivery systems in osteoporosis treatment. Obtained SCXRD and 1H DOSY-NMR data provide a detailed insight into their solid- as well as solution-state structures extending the so far scarcely found X-ray studies on geminal BP-supported Ca(II) complexes.
