    • Side reactions are probably a result of the experimental procedure used: The dichloride complexes are reduced with n-BuLi in the presence of the substrate. Addition of n-BuLi to the ester group may compete with reduction of the dichloride. Catalyst activation in the absence of a substrate also leads to diminished yields, however, because binding of the substrate may inhibit decomposition pathways for the putative Ti(II) species.

    • In this procedure, cannula filtration refers to transferring the liquid from a liquid/solid mixture, under argon, by a stainless steel cannula fitted on one end with a dry glass-fiber filter.
