Description
4,4-Di-tert-butylbiphenyl along with lithium catalyzes:reaction of chloromethyl ethyl ether and different carbonyl compounds to yield corresponding hydroxyethersreductive opening of N-phenylazetidine4,4-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.
