Ultrasound-assisted synthesis of alkali metals diselenides (M2Se2) and their application for the gram-scale preparation of 2,2’-diselenobis(benzoic acid)

A simple and efficient method to convert elemental selenium into alkali metal diselenide was developed. The use of selenium and metal borohydride in a molar ratio of 1 to 0.125 in the presence of base, under “on water” conditions and ultrasound activation permitted the reduction of Se into Se22- to be completed within minutes. Thus obtained metal diselenide aqueous solution was then used in the multigram scale synthesis of 2,2’-diselenobis(benzoic acid) (DSBA) a valuable building block for the development of diverse and pivotal selenorganic compounds.

Synthesis, structural and vibrational analysis of LiMBO3 orthoborates (M = Mg, Co, Zn)

The structure of LiZnBO3 obtained by low temperature hydrothermal reaction has been determined previously in single crystals. We calculated the crystallographic cell of the phases obtained by solid-state reaction without melting by indexing their X-ray powder diffraction patterns. We found evidence that the structure of LiZnBO3 depends on the preparation method. The two structures found are monoclinic probably with the same Li-Zn cationic disorder, as evidenced by vibrational behavior. The cell parameters for the phase prepared at high temperature are a=7.9286(6), b=5.0934(3), c=6.1464(5) A, β = 104.3(5)°, Z=4. The magnesium and cobalt compounds are isomorphous and form a total solid solution. Their monoclinic cells is not related to the cells of the zinc derivative. The parameters of the unit cell are a=9.9155(8), b=8.8847(11), c=5.1577(4) A, β =9 1.231(8)°, Z=8 for the magnesium compound and a=10.1100(7), b=8.8518(8), c=5.1311(6) A, β = 91.358(7)°, Z=8 for the cobalt compound. The lithium cobalt borate is not very thermally stable and it is best synthesized by a two-step procedure. The effect of the lithium isotopic substitution on the vibrational frequencies shows that this cation is in tetrahedral coordination in all the phases. CNRS-Gauthier-Villars.
