The sol-gel prepared SiO2-CaO-P2O5 composites doped with Metronidazole for application in local delivery systems.

Pharm. Dev. Technol. 17(6) , 697-704, (2012)

The aim of this study was to evaluate the physical properties, chemical structure and bioactivity of sol-gel processed oxide (SiO(2)-CaO-P(2)O(5)) composites used as controlled release materials for Metronidazole-drug applied in periodontal disease treatment....

Coordination chemistry of the solvated AgI and AuI ions in liquid and aqueous ammonia, trialkyl and triphenyl phosphite, and tri-n-butylphosphine solutions.

Inorg. Chem. 45(17) , 6912-21, (2006)

The coordination chemistry of solvated Ag(I) and Au(I) ions has been studied in some of the most strong electron-pair donor solvents, liquid and aqueous ammonia, and the P donor solvents triethyl, tri-n-butyl, and triphenyl phosphite and tri-n-butylphosphine....

Synthesis of 1,2-unsaturated pyranosylphosphonate nucleosides from 3,4,6-tri-O-acetyl-D-glycal.

Pharmazie 56(7) , 534-5, (2001)

Ferrier rearrangement of 3,4,6-tri-O-acetyl-D-glucal (1) in the presence of triethylphosphite afforded the 2,3-unsaturated pyranose 2. Deacetylation and simultaneous migration of the double bond to 1,2-position in the sugar moiety was achieved by stirring in ...

Structure of solvated mercury(II) halides in liquid ammonia, triethyl phosphite and tri-n-butylphosphine solution.

Dalton Trans. (17) , 2303-13, (2008)

Liquid ammonia, trialkyl phosphites, and especially trialkylphosphines, are very powerful electron-pair donor solvents with soft bonding character. The solvent molecules act as strongly coordinating ligands towards mercury(ii), interacting strongly enough to ...

Automated analysis of rabbit sperm motility and the effect of chemicals on sperm motion parameters.

Mol. Reprod. Dev. 33(3) , 347-56, (1992)

Appropriate software settings and optimum procedures were determined for the measurement of the motion parameters of rabbit spermatozoa by the CellSoft (Cryo Resources Ltd., Montgomery, NY) computer-assisted digital image analysis system. The system was used ...

Pentanidium-catalyzed enantioselective α-hydroxylation of oxindoles using molecular oxygen.

Org. Lett. 14(18) , 4762-5, (2012)

Pentanidium-catalyzed α-hydroxylation of 3-substituted-2-oxindoles using molecular oxygen has been developed with good yields and enantioselectivities. This reaction does not require an additional reductant such as triethyl phosphite, which was typically adde...

A Useful Synthesis of 1-Aminocyclopropanephosphonic Acid from Cyclopropanone Acetal.

J. Org. Chem. 64 , 4953, (1999)

Copper-catalyzed tandem conjugate addition-electrophilic trapping: ketones, esters, and nitriles as terminal electrophiles.

J. Am. Chem. Soc. 126 , 4528, (2004)

Exposure of enone substrates 1a-18a, which possess appendant ketone, ester, and nitrile moieties, to Et2Zn in the presence of catalytic Cu(OTf)2/P(OEt)3 provides the cyclized products in good to excellent yields and diastereoselectivities. These results repre...

Diazoalkane complexes of ruthenium with tris(pyrazolyl)borate and bis(pyrazolyl)acetate ligands.
