4,4'-DI-TERT-BUTYLBIPHENYL Chemical Properties,Usage,Production

Chemical Properties

Powder

Uses

It is used in the generation of 1,2-di(lithiomethyl)benzene. It is found to accept electrons from Li metal to give a radical anion which is highly effective in the conversion of alkyl halides to alkyllithiums. 4,4?-Di-tert-butylbiphenyl is used in production of homoallylic amine derivatives. It is also used in the preparation of lithium di-tert-butylbiphenylide, a radical anion, superior to sodium or lithium naphthalenides for metalation reactions. Along with lithium, 4,4?-Di-tert-butylbiphenyl catalyzes; reaction of chloromethyl ethyl ether and different carbonyl compounds to yield corresponding hydroxyethers and reductive opening of N-phenylazetidine.

Synthesis Reference(s)

Tetrahedron Letters, 26, p. 1655, 1985 DOI: 10.1016/S0040-4039(00)98576-9

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
