Photochemistry of 2-nitrobenzyl enol ethers: Oxidative C=C bond scission
Yong, Promise K.,Banerjee, Anamitro
, p. 2485 - 2487 (2007/10/03)
(Chemical Equation Presented) 2-Nitrobenzyl enol ethers, when photolyzed in the presence of air, result in an oxidative C=C bond scission, forming a ketone as the major product (>60% yield). Enol release leads to the aldehyde as the minor product.
Three sulfur atom insertion into the S-S bond - Pentasulfide preparation
Hou,Abu-Yousef,Harpp
, p. 7809 - 7812 (2007/10/03)
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.
FTIR Kinetic and Mechanistic Study of the Atmospheric Chemistry of Methyl Thiolformate

Some aspects of the atmospheric chemistry of methyl thiolformate (CH3SCHO), a recently detected intermediate in the oxidation of dimethyl sulfide, have been investigated at 298 K and 1000 mbar total pressure in large reaction chambers using long path in situ FTIR absorption spectroscopy for the analysis.Rate coefficients of (1.11 +/- 0.22)E-11 and (5.80 +/- 0.80)E-11 cm3 molecule-1 s-1 have been determined for its reaction with OH radicals and Cl atoms, respectively.The UV spectrum of CH3SCHO has been measured in the range 220-355 nm and a lower limit of 5.4 days determined for its atmospheric photolytic lifetime.Detailed product analyses have made for the OH and Cl initiated photooxidation of CH3SCHO.Strong SO absorption bands observed in both systems are tentatively assigned to CH3SOCHO in the OH system and to CH3SOCl in the Cl system.The first gas-phase spectra of CH3SCl and CH3SOCl are also presented.The results are discussed with respect to the atmospheric chemistry of CH3SCHO and possible consequences for the photooxidation mechanism of dimethyl sulfide.
A MILD AND CONVENIENT PREPARATION OF SULFENYL CHLORIDES FROM THIOLACETATES

Sulfenyl chlorides are obtained easily and in good yields through the reaction of thiolesters and sulfuryl chloride.
Synthesis and Characterisation of Bispolysulphanes
Mott, Andrew W.,Barany, George
, p. 2615 - 2621 (2007/10/02)
Bispolysulphanes with a linear chain of 1-6 sulphurs have been prepared and characterised; in particular X-ray crystallographic analyses proved the structures of the tri- and tetra-sulphanes.The tri-to hexa-sulphanes were formed by reactions of O,S-dimethyl dithiocarbonate with the appropriate dichlorosulphane containing two less sulphurs.The disulphane was prepared by chlorination of O-t-butyl S-methyl dithiocarbonate or by controlled desulphurisation of the trisulphane using triphenylphosphine; further desulphurisation provided the monosulphide. (Methyl thio)carbonylsulphenyl chloride is proposed as an intermediate in the above chlorination; it was synthesised by an indirect route and shown to rearrange to its isomer, (methylthio)carbonyl chloride.
