摘要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((Pr2P)-Pr-i=S)(C9H6N-2) (3) are reported. The monoanionic thiophosphinoyl lithium complex [Li(Et2O){CH((Pr2P)-Pr-i-S) (C9H6N-2)}](2) (4) and magnesium complex [Mg{CH((Pr2P)-Pr-i-S)(C9H6N-2)}(2)] (5) have been prepared from the reaction of 3 with 1 equiv of (BuLi)-Bu-n or 0.5 equiv of (Bu2Mg)-Bu-n in THF. Metathesis of 4 with 2 equiv of (KBuO)-Bu-t afforded the corresponding polymeric thiophosphinoyl potassium complex [K{CH((Pr2P)-Pr-i-S)(C9H6N-2)}](n) (6). The metathesis reaction of 4 with GeCl2 center dot(dioxane) and PbCl2 afforded the "open-box" 1,3-digermacyclobutane [Ge{mu(2)-C((Pr2P)-Pr-i=S)(C9H6N-2)](2) (9) and "twisted-step" 1,3-diplumbacyclobutane [Pb{mu(2)-C((Pr2P)-Pr-i=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{mu(2)-C((Pr2P)-Pr-i=S)(C9H6N-2)](2) (11) and [Pb{mu(2)-C((Pr2P)-Pr-i=S)(C9H6N-2)](2) (12), respectively. The structures of 3-6 and 9-12 have been determined by X-ray crystallography.
