Clathrate complexes

Iodide and iodate ions react under the influence of protons to yield iodine molecules which react with amylose to yield a blue clathrate complex ... 

However, the starch solution should not be omitted completely since the color difference between the chromatogram zones, in which the iodine is reduced to colorless iodide according to the iodine azide reaction mentioned above, and the background colored brown by unreacted iodine is considerably less than the difference in color between the deep blue background provided by the starch-iodine clathrate complex and the pale chromatogram zones.

Research is currently in progress on free radicals immobilized in supercooled solvents and as clathrate complexes.66 A clathrate complex is a crystal which contains isolated small molecules in regularly spaced cavities of the crystal lattice. These molecules are liberated when the crystal is crushed. 

Aryl sulfenyl chlorides attack the acetylacetonate ring without catalysis. The resulting aryl sulfide chelates (XV) are unusual in that they form remarkably stable clathrate complexes with benzene (26). 

R)-1,1 -Bi-2-naphthol was prepared by resolution employing the N-benzylammonium chloride salt of (-)-cinchonidine to form separable diastereomeric clathrate complexes. Hu, Q-S. Vitharama, D. Pu, L. Tetrahedron Asymmetry 1995, 6, 2123.

There is considerable interest in zinc-ammine complexes as host molecules and several structural studies have been made the clathrate complex [Zn(NH3)4][Ni(CN)4]-0.1PhOH-H2O has been described.131... 

The solid inclusion (clathrate) complex of oxygen with hydroquinone had been prepared twice previously by a published method which involved saturating a solution of hydroquinone in propanol in an autoclave at 70°C with oxygen at 20—150 bar,... 

The trihalides of aluminum are very strong Lewis acids, and AICI3 finds extensive use as a Friedel-Crafts catalyst as a result of this. A wide variety of adducts are known and these exhibit an enormous range of stability, modes of bonding, structures, and properties. Aromatic hydrocarbons and alkenes only interact weakly but crystalline adducts may be isolated, for example, the clathrate complex AlyBrg CeHg. 

The clathrate complex was exposed to cobalt-60 y radiation for 24 h at -80 C for an absorbed dose of 6.5 Mrad to yield 16% of PVF after the urea was washed away with water. PCFE was prepared in urea in a similar manner.

Tris(3-bromoacetylacetonato)chromium(III) is a dark red-brown crystalline material, which dissolves in benzene to form a green solution. The infrared spectrum of this chelate exhibits a characteristic strong singlet at 1540 cm. i, whereas chromium(III) acetylacetonate exhibits two peaks in this region, at 1560 and 1520 cm. b The ultraviolet spectrum of the brominated chromium chelate in chloroform exhibits a Xmax at 358 m/i(e = 13,070). The brominated chelate is reported to form a stable clathrate complex with chloroform (m.p. 240 to 241°). ... 

It has been shown that the cage complex 3 effectively binds various organic guest molecules in its cavity. The structure of the clathrate complex of 3 with the adamantane carboxylate ion has been determined by X-ray crystallography... 

Dr. Soltes has been employed for over 30 years at Academic Research Institutes in Bratislava, Slovakia. His research related to the polysaccharides, which started over two decades ago, resulted in patenting a novel approach "Clathrate complexes formed by hyaluronic acid derivatives and use thereof as pharmaceuticals". His current research interests are focused on the studies of hyaluronan oxidative damage and the regulation of this process. Dr. Soltes is the sole distinguished representative of Slovakia in the International Society for Hyaluronan Sciences. In 2007 he was named Scientist of the Year of the Slovak Republic.
