Jana, Barun published 《Synthesis, characterization and crystal structure determination of aluminum hydride complexes of N,N’-Di(isopropyl)ethylenediamine ligand》. The research results were published in《Journal of Molecular Structure》 in 2021.Safety of rel-(1R,2S)-1,2-Diphenylethane-1,2-diol The article conveys some information:
Reaction of alane-amine adduct, AlH3·NMe2Et, with N,N’-di(isopropyl)ethylenediamine was conducted for the preparation of amide ligated aluminum hydride complexes via dehydrocoupling pathway. Depending on the proportion of the reagents (1:1 and 3:2) two different products (1) and (2) were isolated. Compounds 1 and 2 were characterized using different spectroscopic techniques along with the determination of solid-state mol. structure via single crystal x-ray diffraction studies. In the crystal lattice of complex 2, mols. are connected via weak Al-H…H-C hydrogen bonding supramol. interactions to form polymeric arrangements of the mol. Further, a reaction of 2 with two equivalent of 1,2-diphenylethylene-glycol generated complex 3 that was isolated in trace quantities. Mol. structure of 3 was also determined using single crystal x-ray diffraction study. And rel-(1R,2S)-1,2-Diphenylethane-1,2-diol (cas: 579-43-1) was used in the research process.
Desymmetrization of rel-(1R,2S)-1,2-Diphenylethane-1,2-diol(cas:579-43-1 Safety of rel-(1R,2S)-1,2-Diphenylethane-1,2-diol) using chiral phosphine catalyst has been reported. Conversion of meso-hydrobenzoin to trans-stillbene oxide by treatment with an aryl sulfonyl chloride and aqueous sodium hydroxide has been reported.
