  • Chiral Bora[1]ferrocenophanes: Syntheses, Mechanistic Insights, and Ring-Opening Polymerizations

    unwanted 1,1′‐bis(boryl)ferrocenes 5 were formed. The product ratio depends on the bulkiness of the amino group, the speed of addition of the amino(dichloro)borane, the alkyl group on Cp rings, and in particular on the reaction temperature. The formation of strained [1]FCPs is strongly favored by increased reaction temperatures. Secondly, CHEt2 groups at Cp rings favored the formation of the targeted [1]FCPs

    2 was prepared and applied to some asymmetric reactions. Although a poor enantioselectivity is obtained in the asymmetric allylic alkylation (AAA) of rac-8 using the Pd complex bearing the P,S-hybrid ligand 2, it is noteworthy that this result is superior to that obtained using the C2-symmetric bisphosphine counterpart of 2.

  • Insight into the Formation of Highly Strained [1]Ferrocenophanes with Boron in Bridging Position

    Four planar-chiral, enantiomerically pure ferrocene dibromides (3(R1R2); [((CHRR2)-R-1)BrH3C5](2)Fe) equipped with two (CHRR2)-R-1 groups in a position to bromine were synthesized. From the four C-2 symmetrical species, two are already known [(CHRIR2)-I-1 = CHMe2 (3(MeMe)), CHEt2 (3(EtEt))] and two are new compounds [(CHRR2)-R-1 = R-CHEtMe (3(EtEt)), S-CHMeEt (3(MeEt))]. The dibromides 3(R1R2) were in situ converted into dilithio ferrocene derivatives and reacted with Cl2BNiPr2 resulting in mixtures of bora[1]ferrocenophanes (4(R1R2)) and 1,1'-bis(boryl)ferrocenes (5(R1R2)). The aim of this investigation was to test the hypothesis that the alkyl group that is oriented approximately perpendicular to the Cp ring, i.e., R-2, affects the outcome of the salt-metathesis reaction. The obtained product ratios 4(R1R2):5(R1R2) were determined by H-1 NMR spectroscopy and revealed that systems with the same R-2 group gave similar 4(R1R2):5(R1R2) ratios (1.0:0.51 and 1.0:0.49 for R-2 = Me; 1.0:0.30 and 1.0:0.27 for R-2 = Et), confirming the hypothesis. Shown by DFT calculations (B3PW91/6-311+G(d,p)), reaction paths resulting in either product 4(R1R2) or product 5(R1R2) are both concerted steps.
