Article abstract of DOI:10.1021/om9705057

A number of insertion products, viz., Me₂Al(μ-i-Pr₂N)₂Mg[(t-Bu)NC(CH ₃)S] (1), Me₂Al(μ-i-Pr₂N)₂Mg[(Ph)NC(CH₃)S)] (2), Me₂Al(μ-Et₂N)₂Mg[(t-Bu)NC(CH₃)S] (3), Me₂Al(μ-Et₂N)₂Mg-[(Ph)NC(CH₃)S] (4), {Me₂Al(μM-Et₂N)₂Mg[(Ph)NC(CH ₃)O]}₂ (5), and Me₂Al(μ-i-Pr₂N)₂Mg[SC-(CH₃)S] (6) have been synthesized using polynuclear aluminum-magnesium compounds and various heteroannulenes such as isothiocyanates, isocyanates, and carbon disulfide. All the new compounds were characterized by ¹H and ¹³C NMR, IR, and elemental analysis. The structures of two of the above compounds, 1 and 5, have been determined by single-crystal X-ray diffraction technique.
