General description
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.
Application
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.
