摘要: Lanthanide(II) reagents (SmI2, SmBr2, YbI2, EuI2) have been prepared rapidly in high yields using microwave-assisted heating. Samarium diiodide is obtained as a saturated solution THF (0.13 M) within 5 min and ytterbium (0.065 after 45 min. A simple method for quantitative determination of LnX2 also described by utilizing the instantaneous reaction with ketones presence an amine water. This establishes concentration active single-electron-donor species, i.e. Ln2+. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
