Steric effects on the mode of aggregation and reactivity of clusters formed from the lithiation of trisamidothiophosphates

Steric effects on the mode of aggregation and reactivity of clusters formed from the lithiation of trisamidothiophosphates

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