| 摘 要： | 用SiMe2ClH与Ru3(CO)12反应,得到顺式-Ru(CO)4(SiMe2Cl)2(I)和[Ru(CO)4(SiMe2Cl)]2(Ⅱ)。它们的SiMe2Cl配位基呈现较强的反位效应,由此合成得到一系列含膦(氧磷)或含卤素的衍生物。进行了Ⅰ-Ⅵ的元素分析、IR、1HNMR和MS表征。

| Abstract: | The cholrodimethylsilyl ligand containing derⅣatⅣes of metal carbonyl is believed to be very sensitⅣe in air . The author reports here that the reaction of SiMe2ClHand Ru3(CO)12 gⅣes cis-Ru(CO)4(SiMe2Cl)2( Ⅰ )and [Ru(CO)4(SiMe2Cl)]2( Ⅱ ). The SiMe2Cl ligand in ( Ⅰ ) and ( Ⅱ ) shows the large irons-effect and thus syntheses of a number of derⅣatⅣes of the types mer-M(CO)3 (PR3)(SiMe2Cl)2(X) (Ⅲ) (M=Ru, Os,PR3 = PPh3,ETPB), trans-Ru(CO)4(SiMe2Cl)(X) (Ⅳ) (X=Br, I), [Ru(CO)3(SiMe2Cl)(X)]2 (V), and Ru2(CO)5(SiMenCl3-n)(X)3 (Ⅵ)(n = 1,2; X =C1, Br, I ) are reported. The relationship between geometries and the IRvco band numder are described. Ⅰ -Ⅵ have been characterized by IR, 1H NMRand mass spectrometries. The IRvco band in some of the SiMe2Cl contaning metal carbonyls have been found to be splitted. This may be re-sponsed to the conformational isomeerism of the SiMe2Cl group. |
