Abstract
The molecular structures of title compounds, two of the three isomeric products in the reaction of 2-ethyl-3-phenyloxaziridine with phenyl isothiocyanate, have been determined by means of X-ray diffraction. 4-Ethyl-3,5-bis(phenylimino)-1,2,4-dithiazolidine (6b), orthorhombic, space group Pcab, a=27.171(1), b=10.213(2), c=11.421(1) A, Z=8; 2-Ethyl-4-phenyl-5-phenylimino-1,2,4-thiadiazolidin-3-thione (8b), monoclinic, space group P21⁄n, a=9.278(1), b=27.525(3), c=5.826(1) A, β=92.74(1)°, Z=4. Both structures were solved by the heavy atom method, and refined anisotropically by the block-diagonal least-squares procedure (R=0.066 and 0.060, respectively). The results corrected the reaction scheme proposed for the reaction of N-alkyloxaziridine with phenyl isothiacyanate.
