Iodination of primary alcohol
Webbond underwent iodination in an excellent yield but accompanied by allylic rearrangement. The method can be applied easily for the conversion of primary and secondary saturated alcohols into their iodides in excellent yields (Table 1, entries 10–13). We also studied the iodination of 1-adamantanol as an example of a ter-tiary alcohol. WebIn the the absence of thiourea, oxidation of the alcohol is observed, whereas the substrate can be recovered when excess thiourea is used. Both bromination and chlorination were …
