Abstract |
전이금속 이온인 수은(II) 및 은(I)에 대한 α-케토안정화된 일리드화 인 Ph3P=CHC(O) C6H4-X (X=Br, Ph)의 착물 반응 행동을 연구하였다. 수은(II) 착물 {HgX2 [Y]} 2 (Y1=4-bromo benzoyl methylene triphenyl phosphorane; X=Cl(1), Br(2), I(3), Y2=4-phenyl benzoyl methylene triphenyl phosphorane; X=Cl(4), Br(5), I(6))는 Y1 및 Y2를 HgX2 (X=Cl, Br, I)와 각각 반응시켜 제조하였다. α-케토안정화된 일리드화 인(Y2)의 은(I) 착물 [Ag(Y2) 2] X(X=BF4(7), OTf(8))는 이러한 일리드와 AgX(X=BF4, OTf)를 아세톤에서 반응시켜 얻었다. 착물 (1)과 (4)의 결정구조를 고찰하였다. 일리드의 C-배위 이핵착물과 트랜스-구조의 착물[Y1HgCl2]2. CHCl3 (1) 및 [Y2HgCl2]2 (4)를 형성하는 이들 반응에 대해 단결정 X-선 분석을 통해 고찰 하였다. 모든 착물(1-3)은 IR, 1H 및 31P NMR 뿐만아니라 13CNMR을 통하여 확인하였다.
The complexation behavior of the α-ketostabilized phosphorus ylides Ph3P=CHC(O) C6H4-X (X=Br, Ph) towards the transition metal ions mercury (II) and Silver (I) was investigated. The mercury(II) complex {HgX2 [Y]} 2 (Y1=4-bromo benzoyl methylene triphenyl phosphorane; X=Cl(1), Br(2), I(3), Y2=4-phenyl benzoyl methylene triphenyl phosphorane; X=Cl(4), Br(5), I(6)) have been prepared from the reaction of Y1 and Y2 with HgX2 (X=Cl, Br, I) respectively. Silver complexes [Ag(Y2) 2] X(X=BF4(7), OTf(8)) of the α-keto-stabilized phosphorus ylides (Y2) were obtained by reacting this ylide with AgX (X=BF4, OTf) in Me2CO. The crystal structure of complexes (1) and (4) was discussed. These reactions led to binuclear complexes C-coordination of ylide and trans-like structure of complexes [Y1HgCl2]2. CHCl3 (1) and [Y2HgCl2]2 (4) is demonstrated by single crystal X-ray analyses. Not only all of complexes have been studied by IR, 1H and 31P NMR spectroscopy, but also complexes 1-3 have been characterized by 13CNMR.
