A simple one-pot procedure for the direct conversion of alcohols to azides via phosphate activation was written by Yu, Chengzhi;Liu, Bin;Hu, Longqin. And the article was included in Organic Letters in 2000.Formula: C9H9F3O This article mentions the following:
A one-pot procedure was developed to prepare alkyl azides from the corresponding alkanols using bis(2,4-dichlorophenyl)phosphate activation. 4-(Dimethylamino)pyridine was used as a base, and phosphorylpyridinium azide is believed to be the activating agent under this condition. In the experiment, the researchers used many compounds, for example, 2-(Trifluoromethyl)phenethyl alcohol (cas: 94022-96-5Formula: C9H9F3O).
2-(Trifluoromethyl)phenethyl alcohol (cas: 94022-96-5) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Formula: C9H9F3O
