BRITO, Iván et al. THERMAL AND X-RAY CRYSTALLOGRAPHIC STRUCTURAL STUDIES ON (N,N-DIBENCYL)-4-NITROPHENYLSULFENAMIDE. J. Chil. Chem. Soc. [online]. 2003, vol.48, n.3, pp.51-56. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072003000300010.

Crystal and molecular structure and the thermal properties of (N,N-dibencyl)-4-nitrophenylsulfenamide, (C6H5CH2)2 NSC6H4-4-NO2, is herein presented. The structure is a divalent sulfur compound that crystallized in the monoclinic system, space group P21/c with a=9.274(2), b=6.013(1), c=32.147(9) Å, b=95.55(2) and Dx=1.305 g cm-3 with Z=4. The plane C-S-N form a dihedral angle of 77.4(3) with the plane C19-N1-C20, and it represent a notable difference with other sulfenamides described in the literature. The thermogravimetric analysis reveal a decomposition of the product in two steps and another event, probably, associated to a endothermic phase transition

Palavras-chave : Sulfenamides; sulfenic acid derivatives; divalent sulfur compounds.
