Description

Application

4,4′-Di-tert-butylbiphenyl was used in production of homoallylic amine derivatives. It was also used in the preparation of lithium di-tert-butylbiphenylide, a radical anion, superior to sodium or lithium naphthalenides for metalation reactions.

General description

4,4′-Di-tert-butylbiphenyl along with lithium catalyzes:
  • reaction of chloromethyl ethyl ether and different carbonyl compounds to yield corresponding hydroxyethers
  • reductive opening of N-phenylazetidine
