  • Title: One-pot synthesis of alpha-iodo-substituted alpha,beta-unsaturated aldehydes from propargylic alcohols.
    Author: Chen S, Wang J.
    Journal: J Org Chem; 2007 Jun 22; 72(13):4993-6. PubMed ID: 17523659.
    Abstract:
    An efficient one-pot method for the preparation of alpha-iodo-substituted alpha,beta-unsaturated aldehydes (alpha-iodoenals) from propargylic alcohol is developed. The reaction proceeds via an iodoallene intermediate, which is generated in situ by the reaction of propargylic alcohol with aqueous HI. The iodoallene intermediate is further transformed to an alpha-iodoenal derivative in good overall yield by oxidation with molecular O(2).
