Procedure
This complex was prepared by a modification of the procedure of L. Lombardo, Tetr. Let., 23, 4293 (1982). Titanium tetrachloride (5.75 ml, 0.0523 mol) was slowly added dropwise to a stirred mixture of zinc dust (10.59 g, 0.162 mol) and dibromomethane (4.96 ml, 0.071 mol) in dry tetrahydrofuran (150 ml) at -40° under nitrogen. After the addition, the mixture was warmed to 5° over 30 minutes and then stirred at 5° under argon for 4 days. The slurry was stored at -20° under argon and warmed to room temperature prior to use.
