Hydrogen bonds and halogen bonds operate in concert in the directed assembly of infinite 1-D chains in binary co-crystals of iodine iso-nicotinamide (2 : 2), 1 and tetrafluorodiiodobenzene iso-nicotinamide (1 : 2) 2.

Few studies have been reported on the synthesis of ferrocenesulfonates up to now. Here, we describe use ortho-deprotometalation and “halogen dance” reactions easily reach original derivatives. Further functionalizations using cross-coupling metal/halogen exchange were also performed from iodinated Finally, while electrochemical properties selected evaluated compared with corresponding sulfonami...

Equimolar qu-anti-ties of tetra-ethyl-ammonium chloride (Et4NCl) and 3,4,5,6-tetra-fluoro-1,2-di-iodo-benzene (o-DITFB or o-C6F4I2) have been co-crystallized in a solution of di-chloro-methane yielding a pure halogen-bonded compound, 3,4,5,6-tetra-fluoro-1,2-di-iodo-benzene-tetra-ethyl ammonium chloride (2/1), Et4N(+)·Cl(-)·2C6F4I2, in the form of translucent needles. [(Et4NCl)(o-C6F4I2)2] pack...

Aryl-bromine bonds are successfully cleaved by cobalt(II) porphyrins in basic media to give Co(por)Ar (por = porphyrin) in good yields. Mechanistic studies suggested that the aryl-bromine bond is cleaved through a halogen atom transfer mechanism, which is different from the aryl-halogen bond cleavage mechanism with other group 9 metalloporphyrins.

DFT calculations reveal that halogen bonds and 3c-4e make a difference in the metal-iodylarene chemistry.

A series of four bifunctional ligands based on β-diketonate moieties bearing methyl (2), chloro (3), bromo (4) and iodo (5) substituents and their corresponding Cu(II) complexes have been synthesized and crystallographically characterized in order to explore the possibility of using halogen bonds for the directed assembly of predictable architectures in coordination chemistry. The four ligands ...
