I got the structure back at 6% R factor, which the crystallographer claims is of "better than average quality". I tend to think that the average is 5%, so this would be slightly worse than average quality, but I suppose the crystallographer should know better than I do.
This is the product I have been seeking for so long via the magnesium ligand activation. As mentioned in a previous post I had given up on the magnesium and switched to lithium. This worked like a charm and now that the ligand and metal have come together the fun of derivatizing can begin.
X-ray quality crystals were grown from a slowly evaporated methylene chloride solution.
