Luminescence of CS 3 V 2 O 4 F 5
The luminescence of complex ions like vanadate, niobate and tungstate is well known and has been studied intensively [1]. We have shown that edgeor face-sharing octahedra of this type are luminescent species with high quenching temperatures [2,3]. Examples are Mg4Nb20g and BasSrNb209 with Nb20g8_ anions and Ba3W20g with W2O96anions. These anions consist of face-sharing niobate and tungstate oct...
متن کاملNovel and efficient regioselective enzymatic approach to 3’-, 5’- and 3’,5’-di-O-crotonyl 2’-deoxynucleoside derivatives
Regioselective syntheses of several O-crotonyl 2’-deoxynucleoside derivatives have been efficiently achieved using a biocatalytic methodology. While Candida antarctica lipase B (CAL-B) afforded the 5’-O-acylated compounds, immobilized lipase from Pseudomonas cepacia (PSL-C) provided the 3’-O-crotonylated analogues. Since classical chemical approaches did not work appropriately due to side isome...
متن کاملPoly[diaqua(μ4-3,5-dicarboxylatopyrazol-1-ido-κ6 N 1,O 5:N 2,O 3:O 3′:O 5,O 5′)lanthanum(III)]
In the title coordination polymer, [La(C(5)HN(2)O(4))(H(2)O)(2)](n), the lanthanum(III) metal centre is nine-coordinated, with a distorted tricapped trigonal prismatic geometry, by the O atoms of two water mol-ecules and by two N and five O atoms of two N,O-bidentate, one O,O'-bidentate and one O-mono-dentate 3,5-dicarb-oxyl-ato-pyra-zol-1-ide ligands. The polymeric three-dimensional structure ...

متن کاملSynthesis of 3-deoxy-3,4-didehydro derivatives of 5-O-mycaminosyltylonolide, 5-O-(4-deoxymycaminosyl) tylonolide, and desmycosin.
The 3-deoxy-3,4-didehydro derivatives of 5-O-mycaminosyltylonolide, 5-O-(4-deoxymycaminosyl)tylonolide, and desmycosin have been prepared by treatment of the corresponding 3-O-sulfonyl derivatives with NaI in 2-butanone as the key step. The mechanistic difference in the formation of the 2,3- and 3,4-unsaturated derivatives from the same 3-O-sulfonyl derivative is discussed.
