  can be functionalised. The procedure allows the conversion of aryl diazonium salts, as well as aryl, heteroaryl, vinyl and alkynyl iodonium salts, into the corresponding fluorinated molecules at room temperature. Mechanistic studies were performed to gain a better understanding of the reaction pathway. Under similar conditions, vinyl and aryl iodides, allyl halides, and benzyl bromides were also functionalised

  cross coupling reaction of diethoxyphosphinyldifluoromethylcadmium reagent with aryl iodides was promoted by CuCl under mild conditions to give α,α-difluoro benzylic phosphonates in good yields. A variety of functional groups, including halides, phosphonate, nitro, ketone, carboxylic acid and ester in aryl iodides, could be tolerated. This methodology has been successfully applied to prepare α,α-difluoro

  convenient and effective route for the synthesis of aryl(difluoromethyl)phosphonates has been developed based on cross-coupling reactions. Upon treatment with a stoichiometric amount (or a catalytic amount in some cases) of CuI and CsF, aryl iodides reacted smoothly with (silyldifluoromethyl)phosphonates to give the corresponding aryl(difluoromethyl)phosphonates in good yields.
