Water-bridged H-bonds have been observed in many cases of ligand-receptor recognitions. To explore the roles of water bridges in the binding of neonicotinoids with receptors, twenty-four neonicotinoid compounds with nine fragments, including 1H-1,2,3-tria

Oxidative iodination of deactivated arenes in concentrated sulfuric acid with I2/NaIO4 and KI/NaIO4 iodinating systems
Kraszkiewicz, Lukasz,Sosnowski, Maciej,Skulski, Lech
, p. 1195 - 1199 (2007/10/03)
Deactivated arenes were mono- or diiodinated with strong electrophilic I+ reagents, which were prepared from NaIO4 and either I2 or KI in concentrated H2SO4 (minimum 95% by weight). In general a small excess of the dark brown iodinating solution was used (1.1/1.5 equivalents, for nitrobenzene two equivalents was required). The iodinations were conducted at 25-30 °C with a reaction time of 1-2 hours using either a 'direct' or an 'inverse' method of aromatic iodination to give mono- or diiodinated pure products in 31-91% optimized yields.

A Novel Aromatic Iodination Method, with Sodium Periodate Used as the Only Iodinating Reagent
Lulinski, Piotr,Sosnowski, Maciej,Skulski, Lech
, p. 671 - 675 (2007/10/03)
Benzene, halobenzenes and some deactivated arenes readily reacted in anhydrous NaIO4/AcOH/Ac2O/concd. H2SO4 mixtures to afford, after quenching with excess aqueous Na2SO3 solution (a reducing agent), purified iodinated products in 27-88 percent yields. This novel method of aromatic iodination is simple, fairly effective and environmentally safe.
Synthesis and photochromic properties of substituted 3H-naphtho[2,1-b] pyrans
Gabbutt, Christopher D.,Heron, B. Mark,Instone, Alicia C.,Horton, Peter N.,Hursthouse, Michael B.
, p. 463 - 471 (2007/10/03)
The synthesis and spectroscopic properties of novel 3H-naphtho[2,1-b]pyrans are described. Subtle variation of the colour of the photo-generated merocyanine dyes derived from these naphthopyrans can be accomplished by controlling the steric interactions between a terminal pyrrolidine donor group and a proximal substituent.
Easy, inexpensive and effective oxidative iodination of deactivated arenes in sulfuric acid
Kraszkiewicz, Lukasz,Sosnowski, MacIej,Skulski, Lech
, p. 9113 - 9119 (2007/10/03)
Two 'model' deactivated arenes, benzoic acid and nitrobenzene, were effectively monoiodinated within 1 h at 25-30 °C, with strongly electrophilic I+ reagents, prior prepared from diiodine and various oxidants (CrO3, KMnO4, active MnO2, HIO 3, NaIO3, or NaIO4) in 90% (v/v) concd sulfuric acid (ca. 75 mol% H2SO4). Next, an I2/ NaIO3/90% (v/v) concd H2SO4 exemplary system was used to effectively mono- or diiodinate a number of deactivated arenes. All former papers dealing with the direct iodination of deactivated arenes are briefly reviewed.
