- An efficient procedure for the synthesis of 18O-labelled methanesulfinyl chloride
-
A new procedure for the synthesis of methanesulfinyl chloride is described which involves chlorination of dimethyl disulfide with sulfuryl chloride in the presence of hexamethyldisiloxane. The use of 18O-labelled hexamethyldisiloxane in this reaction results in the formation of 18O-labelled methanesulfinyl chloride. Copyright

- 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.

- Reactions of Thionyl Chloride with Tetraorganotin(IV) Compounds
-
The reactions of thionyl chloride with tetraorganotin(IV) derivatives (R4Sn where R = CH3, C2H5, n-C3H7, n-C4H9, C6H5CH2, C6H4CH3) bring about cleavage of tin-carbon bonds to give dialkyl/aryltin(IV) and alkyl/aryl sulphinyl chlorides.The ease of cleavage observed on the basis of the reactivities of R4Sn follows the order: n-C4H9 > n-C3H7 > C2H5 > CH3 > C6H5CH2 >> C6H4CH3.This order is not the same as commonly known in literature.
