Abstract

The new imino sulfinamidine ligand PhS(NHt-Bu)=NC(Me)=N(C₆H ₃-2,6-iPr₂), LH (11) was synthesized from N-(2,6-diisopropylphenyl)acetamidine (9) and N-tert-butyl phenylsulfinimidoyl chloride (10). Reaction of LH (11) with ZnEt₂ or AlMe₃ gave the complexes LZnEt (12) and LAIMe₂ (13), respectively. The structures of 12 and 13 were determined by X-ray diffraction and were shown to contain L as a κ²-N¹,N⁶ bidentate ligand in a six-membered chelate. Formation of the magnesium complex (LMgN(TMS) ₂·L₂Mg) (14) from 11, MgI₂, and KN(SiMe₃)₂ highlighted a secondary coordination mode of L, binding through the sulfinamidine nitrogens in a four-membered chelate.
