Description
Summary:	碩士 === 國立臺灣大學 === 化學學系 === 82 === The palladium-catalyzed carbon-carbon bond formation in the Heck-type reaction is well-documented. It appears that phosphine ligands play an important role in this reaction.Here, we investigated the ligand effect of the arylation of airylic acid by bromobenzene in the presence of palladium complex, in which the phosphine ligand studied in this reaction including bidentates (dppe and PhP2(23)),tripodal phosphines (P2S(7)、 PO2(9)、P(OH)(OCH3)(13) 、P(OCH3)2(18))。New synthesized PC2 NP(38) ligand reacts with Cr(0), Mo(0), W(0), Rh(I), Ir(I), Pd( II) to form bidentant metal complexes: (PC2NP)Cr(CO)4(49), (PC2 NP)Mo(CO)4(50), (PC2NP)W(CO)4(51), (PC2NP)Rh(NBD)C1(53), (PC2NP) Ir(COD)C1(54), (PC2NP)PdCl2(48).It also reacts with Re2( CO)10(0) to form an isocyanide complex (PC2N)Re2(CO)9(52).
