A highly efficient enantioselective Darzens reaction of aldehydes with diazoacetamides catalyzed by a (+)-pinanediol-Ti(OiPr)4 system has been developed. The cis-glycidic amides were obtained in high yields and with moderate to excellent enantioselectivity (up to 99%).

Cobalt(II) has been determined by extracting with p-nitrobenzoylacetanilide in presence of ammonium sulphocyanide into isobutylmethylketone and measuring the absorbance at 625 nm against solvent blank.Thus, 3 to 50 μg of cobalt has been determined with a relative standard deviation of +/- 0.92percent.The extracting pH of 3 to 4 is maintained by KCl-HCl buffer.The determination is possible in the presence of 37 metal ions commonly associated with cobalt in ores and alloys.Thus, not only the selectivity of the reaction is high, but also the sensitivity, 0.3 ppm, is appreciable.
