Abstract top

In the title compound, [Cu(C17H30N2O2)(C3H7NO)2][SbF6]2, which is a potential catalyst in the asymmetric Gosteli-Claisen rearrangement, the Cu atom adopts a distorted cis-CuN2O2 square-planar geometry arising from N,N'-bidentate coordination by the chiral ligand and two O-bonded dimethylformamide molecules. Two short C-H...O contacts occur within the ligand and two weak intermolecular C-H...F bonds may help to establish the packing.

Comment top

The title compound, (I), was tested as a catalyst in the catalytic asymmetric Gosteli-Claisen rearrangement (Abraham et al., 2001; Abraham & Hiersemann, 2001; Hiersemann & Abraham, 2002; Abraham et al., 2004). The synthesis of the title compound, (I), was accomplished according to a modified procedure of Evans et al. (1999). A sequence of Meyer's amino acid reduction of (S)-tert-Leucine (Meyers & McKennon, 1993), subsequent condensation with dimethyl malonic acid dichloride and p-TsCl catalyzed cyclization provided the (S,S)-t-Bu-box ligand. Treatment of the box ligand with CuCl2 (Evans et al., 1981) and subsequent anion metathesis with AgSbF6 provided [Cu(S,S)-t-Bu-box](SbF6)2. Addition of 2 eq of DMF to a solution of [Cu(S,S)-t-Bu-box](SbF6)2 in 1,2-dichloroethane afforded the bis(N,N-dimethylformamide) complex. Crystallization was achieved by vapor diffusion recrystalization at 243 K.

Experimental top

To a solution of [Cu(S,S)-t-Bu-box](SbF6)2 (15.4 mg, 17.3 mmol, 1 eq) in dry 1,2-dichloroethane (1 ml) under argon atmosphere, DMF (27 µL, 34.6 mmol, 2eq) was added by a microliter syringe and the resulting deep blue solution was stirred for 30 min at room temperature. Subsequent cooling to 243 K for 24 h provided (I) as deep blue crystals. IR (from a 0.05 M 1,2-dichloroethane solution, cm-1): 1750 (w), 1680 (s); UV/vis (from a 0.05 M in 1,2-dichloroethane solution, nm): 255, 733.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
