Selective endo and exo binding of alkali metals to corannulene.
نویسندگان
چکیده
The ion size matters: the structures of corannulene monoanions crystallized with Cs(+) and Rb(+) ions in the presence of [18]crown-6 reveal the intrinsic binding preferences of alkali metals and allow evaluation of the bowl deformation caused by negative charge distribution and metal binding. The large cesium cation coordinates exclusively to the concave face of C(20) H(10)(-), whereas the smaller rubidium cation exhibits convex binding.

Theoretical Study of Exo-Endo Interconversion of [(R)Ca1ixTMS2]Sn
The 1, 3-bis(trimethyl silyl)ether of p-tert-butyl calix[4]arene, Rt-Bu)Ca1ixTMS21112, has beensynthesized and used as a dianionic ligand for "Sn". The complex of [(t-Bu)Ca1ixTMS2]Snexhibits exo and endo isomerism. The structural properties of [(Rp)Ca1ixTMS2]Sn, (Rpara= H,CH3, t-Bu) and the inter conversion of exoendo isomers were investigated by using of SCF-MOPM3 method.
متن کاملPRODUCTION, RELEASE AND THERMAL CHARACTERIZATION OF CELLULOLYTIC ENZYME FROM CELLULOMONAS sp. STRAIN "0"
Cellulase production by a Cellulomonas sp., isolated in 1985 from forest humus soil along the border of the Caspian Sea in Iran, was investigated. This strain secreted endo-and exo-cellulases in the culture medium, but some of the enzymes produced remained cell membrane bound. Cell bound enzymes were released by various treatments. The highest amount of endo-glucanase (up to 95%) and exo-gl...
متن کاملSYNTHESIS OF NORBORNENE FURYL ESTERS AND THEIR ENZYMATIC KINETIC RESOLUTION BY PIG LIVER ESTRASE (PLE)
The reaction of furylacrylic acid with cyclopentadiene in toluene gave the expected Diels-Alder endo-and exo-adductsin -1 : 1 ratio. The adducts were separated by iodolactonization method to provide 3-endo-(2'-furyl) bicyclo 12.2.11 hept-5-ene- 2-exo-carboxylic acid and 3-exo-(2'-fury1)bicyclo 12.2.11 hept-5-ene-2-endocarboxylic acid. Esterification of these acids by MeI / HMPA gave the exp...

Purification of extra-cellular cellulolytic enzymes from C e l l u l o mssp. strain 0, isolated from forest soil in the north of Iran , was studied by using gel filtration and ion-exchange chromatography. Two endo-glucanases (Endo-I & Endo-II) and one exo-glucanase (Exo-I) were purified to hornogenity . The purified enzymes had molecular weights of about 39.000,70.000 and 90.000 daltons for ...
