Descrição

Descrição geral

Barium tert-butoxide is a Brønsted base catalyst that can be used as a precursor of various barium catalysts like barium aryloxide. It can also be used in the preparation of barium diphenylmethanide, applicable in the organometallic chemistry.

Aplicação

Barium tert-butoxide can be used:

• As a catalyst along with various phenolic ligands in the aldol reactions of amides with aldehydes and ketones.
• To prepare yttrium and copper metal complexes by reacting with Y(thd)₃ and Cu(thd)₂, where “thd” is 2,2,6,6-tetramethylheptane-3,5-dione.
• As an initiator along with an alkyl lithium in the butadiene copolymerization reaction.
• In the iridium catalyzed allylic alkylation of non-stabilized enolates.
