Thermochemistry of Perthiyl Radicals
Hawari, J. A.,Griller, D.,Lossing, F. P.
, p. 3273 - 3275 (1986)
Mass spectrometry was used to measure appearance energies for the reaction RSS-t-Bu -> RSS. + t-Bu+ for R = Me, Et, i-Pr, and t-Bu.The data lead to the heats of formation of perthiyl radicals, RSS., and hence to S-C bond dissociation energies in disulfides (ca. 54 kcal mol-1) and to S-S bond dissociation energies for the central bonds of tetrasulfides (32.3 +/- 1.0 kcal mol-1).The appearance energy method was also used to measure the ionization energy of t-BuSS. (8.25 +/- 0.08 eV) and the heat of formation of the ion t-BuSS+ (195 +/- 2 kcal mol-1).
Insertion of a two sulfur unit into the S-S bond - Tailor-made polysulfides
Rys,Harpp
, p. 7169 - 7172 (2007/10/03)
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.
