hexa-coordinated 1:2 adduct [SnMe2Cl2(xantphos)2] in the solid state. However, it dissociates in solution to give the penta-coordinated 1:1 complex [SnMe2Cl2(xantphos)]. Notably, the analogous n-Bu derivative does not react, even under forcing conditions. Finally, the tin(IV) compounds SnR2Cl2 (R = Me, n-Bu) react with dppap [2-(diphenylphosphinoamino)pyridine] to give the penta-coordinated 1:1 adducts [SnR2Cl2(dppap)]
摘要研究了二氯化二有机锡(IV)SnR 2 Cl 2(R = Me,n -Bu)与一系列具有N,P或O供体原子的配体的反应。SnR 2 Cl 2(R = Me,n -Bu)与苯二酮(1,10-菲咯啉-5,6-二酮)和ndppz(11-nitrodipyrido [3,2- a]的双齿螯合吡啶基配体的反应: 2',3'- c ]吩嗪)提供具有通式SnR 2 Cl 2 L(R = Me,n -Bu; L =苯二酮,ndppz)的新的六配位1:1加合物。另一方面,SnMe 2 Cl 2与黄药[9,9-二甲基-4,5-双(二苯基膦基)x吨]反应生成六配位的1:2加合物[SnMe 2 Cl 2(xantphos)2 ]。但是,它在溶液中解离得到五配位的1:1络合物[SnMe 2 Cl 2(xantphos)]。值得注意的是,即使在强迫条件下,类似的n -Bu衍生物也不会反应。最后,锡(IV)化合物SnR
