The influence of a 2-pyridinyl substituent on the catalytic performance of aryl iodides as catalyst in iodine(III) chemistry was explored. An efficient Lewis base adduct between the pyridine nitrogen and the electrophilic iodine(III) center was identified and confirmed by X-ray analysis. This arrangement was shown to generate a kinetically competent superior catalyst structure for the catalytic dioxygenation of alkenes. It introduces the concept of Lewis base adduct formation as a kinetic factor in iodine(I/III) catalysis. (Figure presented.).
CuI/l-proline-catalyzed selective one-step mono-acylation of styrenes and stilbenes

supporting information; experimental part, p. 5771 - 5774 (2010/11/05)
Vicinal di-oxygenation of styrene-type olefins was achieved with cheaper, less toxic CuI in the presence of l-proline as ligand and NaIO4 as the oxidant. This approach provides a straightforward and efficient access to mono-acylated diols from both styrene and stilbene derivatives with good to excellent yields and diastereoselectivity.
Preparation and enantiomer recognition behaviour of azophenolic crown ethers containing cis-1-phenylcyclohexane-1,2-diol as the chiral subunit and 2,4-dinitrophenylazophenol as the chromophore

, p. 383 - 388 (2007/10/03)
Optically active azophenolic crown ethers 1 and 2 incorporating two cis-1-phenylcyclohexane-1,2-diol chiral subunits and a p-(2,4-dinitrophenylazo)phenol moiety as a chromophore have been prepared and the enantiomer recognitive coloration in complexation with chiral ethylamine and 2-aminoethanol derivatives has been examined. The observed enantiomer selectivities of crown ethers 1 and 2 have been interpreted on the basis of CPK molecular model examination of the diastereoisomeric complexes.
