Opis

Opis ogólny

Potassium tert-butoxide is a strong alkoxide base, it can deprotonate carbon and other Brφnsted acids. It is a relatively poor nucleophile.

Zastosowanie

Potassium tert-butoxide has been used as a strong base in the enantioselective synthesis of amines by transfer hydrogenation of N-(tertbutylsulfinyl)imines. It can also be used: To synthesize aliphatic and aromatic amides from corresponding esters and amines. As a base in the intramolecular cyclization of aryl ethers, amines, and amides. As a catalyst to prepare styrene derivatives from aryl halides and alkenes by Mizoroki-Heck reaction.
For general uses, product is also available in powdered form (156671)

Cechy i korzyści

ChemBeads are chemical coated glass beads. ChemBeads offer improved flowability and chemical uniformity perfect for automated solid dispensing and high-throughput experimentation. The method of creating ChemBeads uses no other chemicals or surfactants allowing the user to accurately dispense sub-milligram amounts of chemical.
