Thermal reactions of regioisomeric 1,2,4-trithiolane s-oxides

The products of the gas-phase pyrolysis of two regioisomeric 1,2,4-trithiolane S-oxides were collected in an argon matrix at 1OK and studied by means of spectroscopic as well as computational methods. Whereas the main products of the pyrolysis of the symmetrical S-oxide were identified as thioformaldehyde S-oxide and thioformaldehyde S-sulfide, the non-symmetrical S-oxide gave predominantly dithioformic acid, which exists as a mixture of s-cis and s-trans conformers. We present a rationalization of the reaction pathways including density functional theory computations.

Gas Phase Reactions, 24. The Thermal Generation of Thiocarbonyl Compounds

Thiocarbonyl derivatives R1R2C=S with R1, R2 = H, CH3, C6H5 can be generated thermally in the gas phase from a variety of precursors.Especially advantageous are the cleavage of propene from allyl sulfides or, for their preparation in pure form, the pyrolysis of dithietane or trithiolane derivatives.Photoelectron spectroscopy proves to be well-suited for gas analysis in the flow tube used, for the optimization of the decomposition conditions, and via assignment of the observed ionization patterns for the characterization of the thioaldehydes and thioketones prepared.

Photodissociation of Trimethylene Sulfoxide. Energy Partitioning and the Possible Formation of SO(1Δ)

On direct photolysis or Hg(3P1) sensitized decomposition trimethylene sulfoxide (I) undergoes fragmentation in the gas phase to yield ethylene, propylene, and cyclopropane.There is a nonrandom distribution of the available energy in the cyclopropane-forming reaction which is interpreted to indicate that, in order to conserve spin angular momentum, this reaction channel may be driven to produce SO(1Δ) during direct photolysis, and SO(3Σ) during Hg(3P1) sensitized decomposition.There is a comparison of some aspects of the photochemistry of trimethylene sulfoxide to cyclobutanone photochemistry.
