Three sulfur atom insertion into the S-S bond - Pentasulfide preparation

Chloro(triphenylmethyl)trisulfide (1) reacts under mild conditions with symmetric primary dialkyl disulfides and aromatic disulfides giving pentasulfides as the main products in good yield and selectivity. A mechanism involving a triphenylmethyl alkyl/phenyl tetrasulfide intermediate is discussed. (C) 2000 Elsevier Science Ltd.

Insertion of a two sulfur unit into the S-S bond - Tailor-made polysulfides

Triphenylthiosulfenyl chloride (1) reacts with disulfides RSSR, yielding tetrasulfides as the main products. The results of the insertion for different R groups are reported. A two-step mechanism involving the formation of unsymmetrical trisulfide intermediates containing the trityl group is proposed. (C) 2000 Elsevier Science Ltd.

Nucleophilic substitution of alkyl halides by electrogenerated polysulfide ions in N,N-dimethylacetamide

The reactions between a series of alkyl halides RX: X = I, R = CH3 (1), C3H7 (2); X = Br, R = C4H9 (3), 2-C4H9 (4), 3-C5H11 (5), PhCH2 (6); X = Cl, R = PhCH2 (7), C6H13 (8), and electrogenerated S1/3- ions (S62- ?S3.-) have been investigated by spectroelectrochemistry in N,N-dimethylacetamide at 20°C. RX substrates react in two steps: (i) nucleophilic substitution of S1/3- ions (SN2 process) yielding RSx- ions (x = 5.2, R = alkyl; x = 4.8, R = PhCH2); (ii) subsequent substitutions of RSx- ions lead to RSzR polysulfanes (z ≈ 3.5), probably through partial disproportionation of the anionic species. On a preparative scale, mixtures of CH3SzCH3 (z = 2-6, z = 3.9) or PhCH2Sz CH2Ph (z = 2-5, z = 3.7) were obtained from chemical reactions between 1, 6 and S62- ions, or electrochemical syntheses. Kinetic studies at 20°C of the reactions between S3.- ions and substrates 4, 5, 7 and 8 imply that the dianions S62- are the nucleophilic agents in the first step rather than S3.- radical anions.
