Abstract

Reactions of ZnX2 (X = Cl, Br) with equimolar amounts of Li[t-BuC(NR)2] (R = i-Pr, Cy) yielded mono-amidinate complexes [{t-BuC(NR)2}ZnX]2 (X = Cl, R = i-Pr 1, Cy 2; X = Br, R = i-Pr 3, Cy 4), whereas reactions with two equivalents of Li-amidinate resulted in the formation of the corresponding bis-amidinate complexes [t-BuC(NR) 2]2Zn (R = i-Pr 5, Cy 6). 1 - 6 were characterized by elemental analyses, IR, mass and multinuclear NMR spectroscopy (1H, 13C), and single crystal X-ray analysis (1, 2, 3, 6). In addition, the single crystal X-ray structure of [t-BuC(NCy)2] ZnBr·LiBr(OEt2)2 7, which was obtained as a byproduct in low yield from re-crystallization experiments of 4 in Et 2O, is reported.
