An efficient and selective method for conversion of oximes, semicarbazones and phenylhydrazones to the corresponding carbonyl compounds under solvent-free conditions
o-Xylylenebis (triphenylphosphonium peroxymonosulfate) (1) was easily prepared from an aqueous solution of oxone and o-xylylenebis- (triphenylphosphonium bromide). This Compound (1) is a useful and selective reagent for conversion of oximes, semicarbazones and phenylhydrazones to the corresponding carbonyl compounds. The reaction was carried out under solvent-free conditions and in the presence...

Vibrational Spectra of Tetraphosphorus decasulfide P4S10 The solid state i.r. and the solid an molten state Raman spectra of the cage compound P4S10 have been recorded. An assignment of the vibrational frequencies, mainly based on polarization data, is proposed. For P 4S i 0 an improved preparation method is reported. During melting the P4S10 units remain unchanged but partly lose terminal sulf...
متن کاملSaccharomyces Cerevisiae as a Biocatalyst for Different Carbonyl Group under Green Condition
In this researchsaccharomyces cerevisiae (baker’s yeast) was used as a cheap, readily accessible, selective, efficient, and green bio-catalyst in a chemo selective reduction of carbonyl group to hydroxyl group. In this green procedure three substrates e.g. (3-(3-nitrophenyl)aziridin-2-yl)-1-phenyl-methanone, pyruvate ester, and 2-acetyl-γ-butyrolactone were r...
متن کاملA NEW SPECTROPHOTOMETRIC PROCEDURE FOR THE DETERMINATION OF NICKEL (11) USING 6-PHENYL-2,3-DIHYDRO-AS-TRIAZINE-3 –THIONE
A spectrophotometric procedure for the determination of Nickel (??) based on the complex formation with 6-phenyl-2, 3-dihydro-as-triazine-3-thione (PDTT) was developed. A yellow compound forms and is easily extractable by chloroform at pH>6. The mole ratio between Nickel (??) and PDTT is 1:4. The absorbance of the complex obeys Beer's law over the concentration range of 1-7 ug of Ni (??) pe...
