Fluorinated organic compounds display significant impact in the fields of agrochemicals, pharmaceuticals and materials science. However, very few fluorine-containing compounds are available from nature, and therefore studies of the distinct effect of fluorine substitution mainly depend on the ease of access to fluorinated scaffolds. Among fluorination strategies, the development and application of fluorinated diazo compounds has provided a convenient and effective method for the construction of various fluorinated structural moieties. 展开更多

The lanthanide Schiff base complex [2-OC6H4CHN(2,6-i-Pr2C6H3)]2ErCl(THF) (C42H52ClErN2O3) has been prepared by the reaction of anhydrous LnCl3 with 2 equiv. of the sodium salt of the bidentate Schiff base N-(2,6-diisopropylphenyl)salicylaldimine in THF. The crystal structure was determined by X-ray diffraction analysis. The crystal belongs to triclinic, space group P1 with a = 9.200(1), b = 13.637(2), c = 16.705(2) ? a = 74.493(7), b = 77.979(8), g = 81.306(8), V = 1965.2(4) ?, Z = 2, Mr = 835.60, Dc = 1.412 g/cm3, F(000) = 854, T = 193 K, l(MoKa) = 0.7107 ?and m = 22.38 cm-1. The final R = 0.052 and wR = 0.076 for 8386 observed reflections with I ≥ 2s(I). 展开更多
