Aliphatic fluorine-chlorine exchange reactions can be performed under microwave conditions using TREAT-HF as a mild and selective fluorination reagent. The highly polar TREAT-HF couples efficiently with microwave irradiation and reaction temperatures of 250 °C can be reached within 30 s. Under these conditions dichloromethyl- and trichloromethyl substrates can be converted into the corresponding fluoro analogs within 5 min. In order to prevent corrosion of borosilicate reaction vessel at high temperatures the use of sintered silicon carbide microwave vials is introduced.
Process for the preparation of perhaloalkylthioethers
-
, (2008/06/13)
The present invention relates to a process for the preparation of perhaloalkylthioethers by bringing a perhaloalkyl halide, preferably a bromide or an iodide, into contact with a disulphide in the presence of zinc and of sulphur dioxide or of a dithionite or of a hydroxymethanesulphinate or of a formate anion and sulphur dioxide.
