    • At a ligand to metal ratio of 1, the catalyst becomes slightly less efficient.

    • Small amounts of water also do not effect the catalyst performance.

    • This poisoning was clearly observed by NMR and TLC techniques. A slow decomposition of NH-benzylated norephedrine on refluxing in toluene takes place in the presence of dimethyldimethoxysilane.

    • Contact with air is avoided in all catalytic experiments as it gives rise to a rapid decomposition of the catalyst.

    • note
    • A comparable effect was previously reported in ref. [9]. In this reference, however, a comparison was made between the homogeneous catalyzed reaction at 95% conversion (after a reaction of five days) and the heterogenized analogue at lower conversion. At 95% conversion, the reverse reaction becomes significant and will be favored for the enantiomer formed in excess, hereby decreasing the overall ee.
