Synthetic approaches to polypyridyl bridging ligands with proximal multidentate binding sites
A series of 12 bridging ligands was prepared. These ligands include a central linker appended to two 1,8-naphthyrid-2-yl or two 1,10-phenanthrolin-2- yl units. The linkers include pyridazin-3,6-diyl, 1,8-naphthyrid-2,7-diyl, 2,2?-bipyrid-6,6?-diyl, 1,10-phenanthrolin-2,9-diyl, 1,2-di(2?-pyrid-6?-yl)ethyne, and 3,6-di(2?-pyrid-6?-yl) pyridazine. The ligands were synthesized from the diacetyl derivative of the central linker by a Friedlaender condensation with either 2-aminonicotinaldehyde or 8-amino-7-quinolinecarbaldehyde. The precursor diacetyl derivatives were, in turn, prepared by pathways involving Stille and Sonogashira couplings. Examination of the electronic absorption spectra of the bridging ligands shows the strongest correlation to be between pairs of ligands having the same central linker. Complexation studies will follow.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 141-30-0, and how the biochemistry of the body works.HPLC of Formula: C4H2Cl2N2
