碩士 === 國立臺北科技大學 === 有機高分子研究所 === 101 === (a) Synthesize a series of the small fluoro-ponytailed bipyride ligands [4,4’-bis(RfCH2OCH2)-2,2’-bipyridine and 5,5’-bis(RfCH2OCH2)-2,2’-bipyridine，Rf= CF2（2F）, CF3（3F）, CF2CF2H（4F）, CF2CF3（5F）, (CF2)2CF3（7F）, (CF2)3CF2H（8F）] amd their complexes（These ligands react with PdBr2, PtCl2, PtBr2 and PtI2） These complexes have been characterized by NMR（1H, 13C, 19F）, IR, High-resolution mass spectrum（HR-FAB）, X-ray diffraction and melt point, then compared their characters each other. (b) The complexes intercalated ZrP（Zirconium phosphate）will make new recycling catalysts for the Sonogashira reaction. The catalysts have good catalytic effect in the test, but its effect will reduce after the recycle. We think that the complexes dissolve in the solvent, then desorb from ZrP. The catalysts are much less than before, reducing the reactive rate.
