  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

  The copper-catalysed zinc phosphonate chemistry described by Yokomatsu and Shibuya can be used to enter the classical organometallic coupling repertoire via Stille and Suzuki–Miyaura couplings. 1,4-Diiodobenzene underwent coupling with the organozinc reagent derived from diethyl bromodifluoromethylphosphonate with copper(I) catalysis to afford diethyl (4-iodophenyl)difluoromethylphosphonate. Higher yielding couplings were run with (4-trifluoromethylsulfonyloxy)- and (4-nonafluorobutylsulfonyloxy)-iodobenzenes. The iodide and the triflate coupled under palladium-catalysed conditions with a range of stannanes and boronic acids in moderate to excellent yields. Shibuya–Yokomatsu couplings were also successful with more functionalised iodoarenes and heteroarenes presenting the important phosphate mimic on a range of scaffolds.

  横松和渋谷描述的铜催化锌膦酸酯化学可用于通过斯蒂尔（Stille）和铃木-宫浦（Suzuki-Miyaura）偶联反应进入经典的金属有机偶联反应领域。1,4-二碘苯在铜(I)催化下与由二乙基溴二氟甲基膦酸酯衍生的有机锌试剂发生偶联，生成二乙基(4-碘苯基)二氟甲基膦酸酯。与(4-三氟甲磺酰氧基)和(4-九氟丁磺酰氧基)碘苯进行的偶联反应产率更高。碘化物和三氟甲磺酸酯在钯催化条件下与一系列锡烷和硼酸发生偶联，产率从中等到优异。渋谷-横松偶联反应在具有更丰富官能团的碘芳烃和杂芳烃上也取得了成功，这些重要磷酸类似物被引入多种骨架上。

This novel photochemical method was successfully extended to aromatic and heteroaromatic substitutions to provide the corresponding α-aryl-α,α-difluoroacetates and α-aryl-α,α-difluoromethylphosphonates in good to moderate yields.
