Copper(I) complexes with thioether-functionalized Silylamido ligands

Abstract

The thioether-functionalized aminosilanes Me2Si(NH-C6H4-2-SR)2 (R=Ph, Me) were lithiated with n-BuLi and subsequently allowed to react with CuCl in the presence of PMe3. In the case of Me2Si(NH-C6H4-2-SPh)2, the dinuclear complex [Cu2{Me2Si(NC6H4-2-SPh)2}(PMe3)2] was isolated. In [Cu2{Me2Si(NC6H4-2-SPh)2}(PMe3)2] the copper atoms adopt a distorted trigonal-planar coordination (Cu−N: 191.2(2) pm, Cu−P: 216.3(1) pm, Cu−S: 244.4(1) pm). The reaction of Li2Me2Si(N-C6H4-2-SMe)2 with CuCl in the presence of PMe3 led to rearrangement processes from which the ionic cluster compound [Cu(PMe3)4][Cu5{Me2Si(N-C6H4-2-S)(N-C6H4-2-S−Me)}2(PMe3)2] was isolated in low yield.
