Bisindole[3]arenes—Indolyl Macrocyclic arenes Having Significant Iodine Capture Capacity

Iodine-catalyzed ammoxidation of methyl arenes.

The development of organic transformation using cheap and readily available substrates under mild conditions will be pivotal for green and sustainable synthetic organic chemistry. Concerning our continued interest in the cyanation reaction, a metal-free direct ammoxidation of readily available methyl arenes leading to nitriles was established under mild conditions. A series of aryl methanes esp...

Complexity, Capacity, and Capture

Biomimetic macrocyclic receptors for carboxylate anion recognition based on C-linked peptidocalix[4]arenes.

Two neutral macrobicyclic anion receptors 4 and 6, containing a calix[4]arene in the cone conformation, two l-alanine units, and a 2,6-diacylpyridine or a phthaloyl bridge, are described. The x-ray crystal structure of the acetone complexes of the pyridine containing macrocycle 6 shows the four amide NH groups to be in close proximity to the chiral pocket delimited by the pyridine and one aroma...

High-yielding one-pot synthesis of diaryliodonium triflates from arenes and iodine or aryl iodides.

Unsymmetric and symmetric diaryliodonium triflates are synthesized from both electron-deficient and electron-rich substrates in a fast, high yielding, and operationally simple protocol employing arenes and aryl iodides or iodine.

Selective capture of volatile iodine using amorphous molecular organic solids.

A simple shape-persistent organic molecular container is capable of selective absorption and storage of I(2(g)) over water vapor and NO gas even in its amorphous solid state. In addition, the strongly associated I(2) can be efficiently released from the charged container in organic solvents under ambient conditions.
