Abstract
The synthesis and structural characterization of lithium, magnesium, potassium, and a series of low-valent group 14 metal compounds derived from the novel 2-quinolyl-linked phosphoranosulfide CH2(iPr2P═S)(C9H6N-2) (3) are reported. The monoanionic thiophosphinoyl lithium complex [Li(Et2O){CH(iPr2P–S)(C9H6N-2)}]2 (4) and magnesium complex [Mg{CH(iPr2P–S)(C9H6N-2)}2] (5) have been prepared from the reaction of 3 with 1 equiv of nBuLi or 0.5 equiv of nBu2Mg in THF. Metathesis of 4 with 2 equiv of KtBuO afforded the corresponding polymeric thiophosphinoyl potassium complex [K{CH(iPr2P–S)(C9H6N-2)}]n (6). The metathesis reaction of 4 with GeCl2·(dioxane) and PbCl2 afforded the “open-box” 1,3-digermacyclobutane [Ge{μ2-C(iPr2P═S)(C9H6N-2)]2 (9) and “twisted-step” 1,3-diplumbacyclobutane [Pb{μ2-C(iPr2P═S)(C9H6N-2)]2 (10), respectively. Reaction of 3 with 1 equiv of M{N(SiMe3)2}2 (M = Sn, Pb) afforded the corresponding “open-box” 1,3-distannacyclobutane [Sn{μ2-C(iPr2P═S)(C9H6N-2)]2 (11) and [Pb{μ2-C(iPr2P═S)(C9H6N...
