One-Pot C?H Functionalization of Arenes by Diaryliodonium Salts
Reitti, Marcus,Villo, Piret,Olofsson, Berit
, p. 8928 - 8932 (2016/07/26)
A transition-metal-free, mild, and highly regioselective synthesis of nitroarenes from arenes has been developed. The products are obtained in a sequential one-pot reaction by nitration of iodine(III) reagents with two carbon ligands, which are formed in situ from iodine(I). This novel concept has been extended to formation of aryl azides, and constitutes an important step towards catalytic reactions with these hypervalent iodine reagents. An efficient nitration of isolated diaryliodonium salts has also been developed, and the mechanism is proposed to proceed by a [2,2] ligand coupling pathway.
Metal-Free C-Arylation of Nitro Compounds with Diaryliodonium Salts
Dey, Chandan,Lindstedt, Erik,Olofsson, Berit
, p. 4554 - 4557 (2015/09/28)
An efficient, mild, and metal-free arylation of nitroalkanes with diaryliodonium salts has been developed, giving easy access to tertiary nitro compounds. The reaction proceeds in high yields without the need for excess reagents and can be extended to α-arylation of nitroesters. Nitroalkanes were selectively C-arylated in the presence of other easily arylated functional groups, such as phenols and aliphatic alcohols.
Halogen exchange via a halogenation of diaryliodonium salts with cuprous halide
Li, Jian,Liu, Li,Ding, Dong,Sun, Jiang-Tao
, p. 541 - 548 (2014/01/06)
An efficient halogenation reaction has been developed with diaryliodonium salts and cuprous halides. Various diaryliodonium salts 1 could perform the reaction with readily available CuBr or CuCl in CH3CN at 80°C, assembling bromoarenes or chloroarenes in up to 92% yields. This provides us a method for the transformation from iodoarenes to other haloarenes.
