25 Acetal 30.1 was the paradox that with Lewis acid and underwent an ene macrocyclization to furnish ether 30.2 with pure (R)-configuration at C15. Removal of the sidechain was achieved via oxidation to the methyl ketone and retro oxa-Michael reaction to obtain alcohol 30.3, which was ...
“Grignard’s solution”), yields, after reaction with H2O, trimethylcarbinol (CH3)3COH, a tertiary alcohol, with ethyl thioalcohol and hydrogen chloride dry, yields mercaptol (CH3)2C(SC2H5)2, with hypochlorite, hypobromite, or hypoiodite solution, yields chloroform CHCl3, bromoform CHBr3 ...
electrochemical reactionsElectrochemical reduction of acetone on Hg was studied in NaOH aqueous solution at 25°C. The potentiodynamic study showed that the reaction intermediate is the sodium formed by the discharge of Na + . Kinetics and mechanism are discussed....
methyl iodide in anhydrous ether (“Grignard’s solution”), yields, after reaction with H2O, trimethylcarbinol (CH3)3COH, a tertiary alcohol, with ethyl thioalcohol and hydrogen chloride dry, yields mercaptol (CH3)2C(SC2H5)2, with hypochlorite, hypobromite, or hypoiodite solution, yields ...

The raw pH -data, obtained from the potentiometric titrations of the titled ligands with NaOH in 75% ( v/v ) dioxane-water mixture performed at 20, 30 and 40°C at constant ionic strength (μ=0.1 M -NaClO 4 ), have been adequately corrected for dilution, and solvent effects in order...
It means that europium(III) thenoyltrifluoroacetone complex does not influence the oxidation rate of hydroxylamine and indicates its important role in this reaction as a sensitiser. A possible mechanism of the chemiluminescence of the NH2OH-OH-NaOH-CU(II)Eu(III) chelate system is presented....
