Insertion reactions of carbon disulfide into Mg-C and Mg-N bonds: Syntheses and structural determinations of Mg(S2CY)2(THF)n (Y=NEt2, NiPr2, ipr, Ph) and BrMg(S2CZ)(THF)3 (Z=Ph, iPr)

The insertion reaction of CS2 with Mg(NR2)2 (R= Et, i Pr), MgR2 (R= Et, Ph) and RMgBr (R= i Pr, Ph) respectively lead solid products, Mg(S2CNR2)2(THF)n (1: R= Et, n=2; 2 :R = i Pr, n=1), Mg(S2CR)2(THF)2 (3: R= Et,4: R= Ph), BrMg(S2CR) (THF)3 (5: R= i Pr,6: R= Ph) in which the inserted carbon disulfides act as terminal chelating ligands. These compounds were characterized with 1 H, 13 C NMR, IR spectroscopy, mass
