  Structure and chemistry of chloro(triphenylmethyl)sulfanes

  摘要：

  The structures of chloro(triphenylmethyl)mono-, di-, and -trisulfanes were obtained. The monosulfane displayed a triclinic (P1) space group, a = 10.792(2) Angstrom, b = 15.090(2) Angstrom, c = 10.027(2) Angstrom, alpha = 100.15(1)degrees, beta 103.13(1)degrees, gamma = 88.80(1)degrees, Z = 4. The disulfane gave a triclinic (P1) space group, a = 9.758(1) Angstrom, b = 10.426(2) Angstrom, c = 9.1691(6) Angstrom, alpha = 97.52(1)degrees, beta = 90.116(1)degrees, gamma = 116.750(1)degrees, Z = 2. The trisulfane gave an orthorhombic space group (Pna2(1)), a = 9.224(1) Angstrom, b = 19.196(3) Angstrom, c = 10.308(1) Angstrom, Z = 4. The sulfenyl chlorides decompose above their melting points to mixtures consisting primarily of triphenylchloromethane and sulfur. The sulfur was determined to consist of several allotropes (S-6, S-7, S-8, and S-9). The di- and trisulfanes slowly decompose to the same products at room temperature; the decompositions are enhanced by light. The decomposition of the trisulfane in the presence of dienes gave adducts consistent with the transfer of a two-sulfur species. The disulfane and trisulfane undergo the normal nucleophilic substitution reactions of the monosulfanes.
