  The presented method allows the preparation of ipso-phosphonodifluoromethylarenes utilizing a heterobimetallic catalytic system of nickel and copper. The protocol represents an advantage over traditional palladium catalysed Suzuki coupling due to the short reaction times and the use of earth-abundant metals.

  所提出的方法允许利用镍和铜的异质双金属催化体系制备异膦酰基二氟甲基芳烃。由于反应时间短和使用地球上丰富的金属，该协议比传统的钯催化 Suzuki 耦合具有优势。

  Anodic fluorination of benzylphosphonate derivatives was carried out under various electrolytic conditions to provide the corresponding alpha-mono- and/or alpha,alpha-difluoro-products in moderate to good yields. It was found that the selectivity of fluorinated products was depending on the molecular structures of the starting substrates and the electrolytic conditions. (C) 2006 Elsevier B.V.

  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.
