Please log in or register to add a comment. To prepare di tert-butyl ether by Williamson’s synthesis, we need tert-butyl bromide and Sodium tertiary butoxide. Therefore the addition of a Grignard reagent can take place on either face of … Ethyl, isobutyl, ethyl tert-butyl, and ethyl tert-pentyl ether are particularly hazardous in this respect. No sort of t-butyl ether (methyl, ethyl, propyl, etc.) can be made with the Williamson synthesis simply because the Williamson synthesis is just a...
