Synthesis of dialkylscandium complexes supported by β-diketiminato ligands and activation with tris (pentafluorophenyl)borane

Treatment of ScCl3·THF3 with the lithium salts of the ligands ArNC(R)CHC(R)NAr, where Ar = 2,6-Pr1-C6H3 and R = CH3 and But, gives LScCl2·nTHF derivatives (R = CH3, n = 1, 1a; R = But, n = 0, 1b). These compounds can be derivatized by alkylation with methyllithium or benzylpotassium. The dibenzyl compound prepared from 1a, when treated with B(CcFc)S, gives an ion pair, 4, in which the cationic scandium center is stabilized by a η6-aryl interaction with the abstracted borate benzyl group.

Dialkylscandium complexes supported by β-diketiminato ligands: Synthesis, characterization, and thermal stability of a new family of organoscandium complexes

Several diorganoscandium complexes stabilized by the β-diketiminato ligands (Ar)NC(R)-CHC(R)N(Ar) (Ar = 2,6-iPr-C6H3; R = CH3 (ligand a), R = tBu (ligand b)) have been synthesized. Reaction of the lithium salts of the ligands with ScCl3·3THF leads to the complexes LScCl2(THF)n, which may be readily alkylated to form the dialkyl derivatives. Most are isolated as base-free, four-coordinate complexes. Several have been characterized via X-ray crystallography, and a detailed discussion of their structures is presented. Steric interactions between Ar and the Sc-alkyl groups force the scandium to adopt an out-of-plane bonding mode. In solution, this is manifested via a fluxional process which equilibrates the two diastereotopic alkyl groups and ligand groups as well. The barriers to this process roughly correlate with the steric bulk of the alkyl substituents. At elevated temperatures, the dialkyl derivatives LScR2 undergo a metalation process whereby one of the alkyl groups is eliminated as RH, and a ligand iPr group is metalated in the methyl position. These reactions are first order in scandium complex, and activation parameters of ΔH? = 19.7(6) kcal mol-1 and ΔS? = -17(2) cal mol-1 K-1 were measured for the loss of Me4Si from (Ligb)-Sc(CH2SiMe3)2.
