A Procedure for Gas-Phase Dehalogenation of Organic Dihalides with Alkali Metal Vapors Using Microwave and/or Ultrasound Excitation and Matrix Isolation of Products

Article abstract of DOI:10.1021/jo00179a022

Gas-phase dehalogenation of organic dihalides with alkali metal vapors in excess argon is promoted by microwave and/or ultrasound excitation.The products were deposited on a cold window along with excess solid argon.The use of the method is demonstrated on three α,ω-diiodoalkanes.The procedure is useful for the preparation of small amounts of highly strained olefins and ring compounds from their dihalo precursors.
