Phosphinethiolate tin(IV)-11 group-metal derivatives. X-ray structure of [Au2Sn(tBu)2(C6F5)2(SC6H4PPh2)2]
摘要:
[SnR2Cl2] reacts with (SC6H4PPh2)(-) giving [SnR2(SC6H4PPh2)(2)] (R = Me, Bu-t, Ph) (1a-c). These compounds can displace tetrahydrothiophene from [Au(C6F5)(tht)] or [Au(tht)(2)]ClO4 or reacts with AgClO4. Complexes [SnR2{(SC6H4PPh2)Au(C6F5)}(2)] (2a-c) and [SnR2(SC6H4PPh2)(2)M]ClO4 (M = Au 3a-c; M = Ag 4a-c) are obtained. The crystal structure of [Sn(Bu-t)(2){(SC6H4PPh2)Au(C6F5)}(2)] (2b) has been established by X-ray diffraction. (C) 1999 Elsevier Science S.A. All rights reserved.
[Sn(R)2(Ph 2 PC 6 H 4 -2-S)2 ]与第10组金属配合物的金属转移反应:立体选择性合成顺式-[M(Ph 2 PC 6 H 4 -2-S)2 ](M = Ni,Pd,Pt)
摘要:
配合物的顺式- [M(PH 2 PC 6 H ^ 4 -2-S)2 ] M =镍,钯,铂被立体选择性地通过的金属转移反应合成[M(Cl)的2(NCC 6 ħ 5)2 ] M =具有[Sn(R)2(Ph 2 PC 6 H 4 -2-S)2 ]的Pd,Pt或NiCl 2 ·6H 2 O R = Ph,n Bu或t卜 通过单晶X射线衍射研究明确证实了Pd和Pt衍生物的构型,结果表明两个金属中心都处在稍微扭曲的方形平面环境中,主要变形是由于磷化氢中的芳环引起的空间位阻部分。
