The tosylate of (2S, 3S)-3-phenylbutan-2-ol undergoes an E2 elimination on treatment with sodium ethoxide. Draw the structure of the alkene that is produced. Use the wedge/hash bond tools to indicate stereochemistry. You do not have to explicitly draw H atoms. If a group is achiral, do not use wedged or hashed bonds on it.

Amines are converted into alkenes by a two-step process called the Hofmann elimination. S2 reaction of the amine with an excess of CH I in the first step yields an intermediate that undergoes 2 reaction when treated with silver oxide as a base. Pentylamine, for example, yields 1-pentene. 1. excess CHI CH3CH2CH2CH2CH2NH2 240,0 HO CH3CH2CH2CH=CH2 Propose structures for the intermediate and the alkene produced in steps 1 & 2 when the following compound undergoes Hofmann elimination: CH3CH2CH(NH2)CH2CH3 - Intermediate -...
Amines are converted into alkenes by a two-step process called the Hoffman elimination. SN2 reaction of the amine with an excess af CH3l in the first step yields an intermediate that undergoes E2 reaction when treated with silver oxide as a base. Pentylamine, for example, yields 1-pentene excesS CH3CH2CH2CH2CH2NH2 CH3CH2CH2CH-CH2 2. Ag20, H20 Propose structures for the intermediate and the alkene produced in steps 1 & 2 when the following compound undergoes Hoffman elimination: CH(CH3)2CH2NH2 Do not consider stereochemistry.
