Tertiary butoxide
WebThe tert-butoxide is a strong, non-nucleophilic base in organic chemistry. It readily abstracts acidic protons from substrates, but its steric bulk inhibits the group from participating in nucleophilic substitution, such as in a Williamson ether synthesis or an S N 2 reaction. tert-Butyl alcohol reacts with hydrogen chloride to form tert-butyl ...
