Synthesis and reactivity of a terminal scandium imido complex

Preparation of a terminal scandium imido complex, 2·DMAP, was accomplished through thermolysis of an arylamido methyl complex, 1, stabilized by a bulky β-diketiminato ligand in the presence of 4-N,N- dimethylaminopyridine (DMAP). Mechanistic studies revealed that the reaction proceeds by initial metalation of 1, followed by rapid DMAP-promoted alkane elimination to generate the scandium imido complex. Kinetic studies of the reaction between separately synthesized metalate 3 and DMAP under pseudo-first-order conditions yielded activation parameters of ΔH a = 73.5(2) kJ mol-1 and ΔS a = -70.4(5) J K-1 mol-1. The reaction of 2·DMAP with tert-butyl amine or phenylacetylene resulted in addition of the N-H or C-H bond across the scandium imide linkage, respectively, to furnish complexes endo-/exo-4 and endo-5. These compounds were fully characterized, including via structural analysis, providing further evidence for the terminal scandium imido derivative 2·DMAP.
