The acetonitrile‐solvated [(MeCN)Ni(C2F5)3]− was prepared in order to compare and contrast its reactivity with the known [(MeCN)Ni(CF3)3]− towards organic electrophiles. Both [(MeCN)Ni(CF3)3]− and [(MeCN)Ni(C2F5)3]− successfully react with aryl iodonium and diazonium salts as well as alkynyl iodonium salts to give fluoroalkylated organic products. Electrochemical analysis of [(MeCN)NiII(C2F5)3]− suggests...
The Ni‐catalysed cross‐coupling of aryl ethers is a powerful method to forge new C−C and C−heteroatom bonds. However, the inert C(sp2)−O bond means that a canonical mechanism that relies on the oxidative addition of the aryl ether to a Ni0 centre is thermodynamically and kinetically unfavourable, which suggests that alternative mechanisms may be involved. Here, we provide spectroscopic and structural...
