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 -...

How to properly solve these elimination and addition
reactions
Elimination and Addition reactions Purpose: Figuring out the ways that molecules react is the province of the mechanistic chemist. By understanding the mechanisms of reactions, the chemist can manipulate the experimental variables to favor one product over another. This element of control is the province of the synthetic organic chemist. This Workshop continues to explore how we know how molecules react and how this knowledge leads to control of the products....
