Application

Selective Deprotonations using Knochel-Hauser-Base
2,2,6,6-Tetramethylpiperidinylmagnesium chloride lithium chloride complex is a non-nucleophilic Knochel-Hauser base mainly used for the magnesiation of functionalized arenes and heteroarenes to prepare the corresponding Grignard reagents. It can also be used as a base in the synthesis of Π-conjugated polymers via catalyst-transfer polycondensation.

Packaging

The 25 mL Sure/Seal™ bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.
