  Synthesis and thermal behavior of dimethyl scandium complexes featuring anilido-phosphinimine ancillary ligands

  摘要：

  A family of N,N donor ligands [1-(NHAr)-2-(PR2= NAr')C6H4] (1a-d; Ar = 2,6-Pr-i(2)-C6H3, R = Me, Ph, Ar' = 2,4,6-Me-3-C6H2, 2-Pr-i-C6H4, 2,6-Pr-i(2)-C6H3) has been prepared and fully characterized by multinuclear NMR spectroscopy and X-ray crystallography. Lithiation of the N-H unit and subsequent salt metathesis protocols with ScCl3THF3 provides an avenue to organometallic scandium complexes. The resultant base-free monomeric dichlorides LScCl2, 3a-d, have been fully characterized by NMR spectroscopy as well as X-ray crystallography (3a,c,d). Alkylation of the dichlorides using LiMe results in clean formation of dialkyl complexes LScMe2 4a-c. Thermolysis of these materials under argon and hydrogen leads to decomposition products as a result of C-H activation of the ligand. Analysis of these results provides a qualitative assessment of the metalative resistance of each ligand framework. (C) 2007 Elsevier B.V. All rights reserved.
