DESCRIPTION
General description
This material is in a solution of THF/Hexanes (ca. 1:7 ratio, respectively)
Application
Titanium-ate enolates prepared from ketones by Ti(OiPr)4 and LDA underwent efficient radical trifluoromethylation providing trifluoromethyl ketones in good yield.[1] Used in directed ortho-lithiation of arylsulfonyloxazolidinones to prepare N-substituted saccharin analogs.[2]
Packaging
The 25 mL Sure/Seal™ bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.
