Crystal structure of 3,5-diaza-methyl-2-methyl-6-oxo-6-phenyl-4- thioxohexanoate, at 200 K, C12H14N2O3S

The crystal structure of benzeneseleninic acid anhydride, C12H10O3Se2

“…A number of substrates in this context benefit significantly from the catalytic action of seleninic acids [7][8][9]. In continuation of our interest in structureproperty relationships of esters [10][11][12][13][14] a preparative study aimed at the synthesis of novel esters was initiated. To prevent accidental isolation of the anhydride of benzeneseleninic acid (that was used as a precursor to generate the catalytically-active benzeneseleninic acid in situ) it was subjected to a diffraction study.…”
