摘要：

Lithiation of SP[N(H)R](3) with LiBun produces the dimers [(THF)LiSP(NR)(NHR)(2)](2) (R = Pr-i) or {[LiSP(NR)(NHR)(2)][(THF)LiSP(NR)(2)(NHR)]}(2)(R= Bu-t) with central Li2N2 or Li2S2 rings, respectively; further lithiation yields the dianion [SP(NR)(2)(NHR)](2)- (R = Pr-i) or leads to sulfur extrusion when R = Bu-t.
