- A straightforward approach to synthesizing substituted 1,3-alkadien-2-yl carboxylic acids starting from readily available propargylic alcohols was developed. Based on mechanistic studies, the reaction was found to proceed via regioselective hydrocarbonylation of the C–C triple bonds of the in situ formed 1,3-enyne intermediates, providing 1,3-alkadien-2-yl carboxylic acids with a very high selectivity.
