Studies on sulfinatodehalogenation: XVI. Sodium dithionite‐initiated addition of perfluoroalkyl iodides to terminal alkynes
View through CrossRef
AbstractReaction of perfluoroalkyl iodides with a series of alkynes under sulfinatodehalogenation condition gave a mixture of E/Z adducts very readily in high yield, thus constituted a mild, convenient and effective new method for the addition of perfluoroalkyl iodides to alkynes. Under the same condition, in the presence of 1‐hexyne perfluoroalkyl bromide and 1,1,1‐trichlorotrifluoroethane reacted only to give sulfinates as the major products. A radical mechanism was proposed for the addition reaction.
