Generation and Reactions of Trifluoromethylethenyl Titanium(II) Species
摘要:
The reaction of (trifluoromethyl)dimethylphenylsilyacetylene and (eta(2)-propene)Ti((OPr)-Pr-i)(2) generated in situ smoothly proceeded giving the corresponding (eta(2)-1-dimethylphenyl-silyl-2-trifluoromethylalkyne)Ti((OPr)-Pr-i)(2), which reacted with aldehydes and ketones to afford the corresponding addition products in good yields with good to excellent regioselectivity.
