O-benzyl-N-(2-furoil)tiocarbamate, Luis Alberto Montiel Ortega, Susana Rojas-Lima, Elena Otazo-Sánchez y Roberto Villagómez-Ibarra, Journal of Chemical Crystallography, 34, 89-93 (2004).
The O-benzyl-N-(2-furoyl)thiocarbamate (1) was obtained by direct reaction between furoyl isothiocyanate and benzyl alcohol. The X-ray diffraction analysis of 1 showed an orthorhombic system, with aD7.811(4) A, bD9.685(4) A, cD33.562(15) A, and space group P212121. This compound showed two different arrays of structure, corresponding to two conformers in the same crystal unit. In one conformer the carbonyl and thiocarbonyl groups are in a syn arrangement while in the other the groups are anti. Both structures present a non-restricted conformation and show NH OC hydrogen bonding between them.
