Generation and reactions of trifluoromethylethenyl titanium(II) species.
The reaction of (trifluoromethyl)dimethylphenylsilylacetylene and (eta(2)-propene)Ti(O(i)Pr)(2) generated in situ smoothly proceeded giving the corresponding (eta(2)-1-dimethylphenylsilyl-2-trifluoromethylalkyne)Ti(O(i)Pr)(2), which reacted with aldehydes and ketones to afford the corresponding addition products in good yields with good to excellent regioselectivity.
