HCl Elimination from Ethanesulfenyl Chloride and Chlorodimethyl Sulfide Thioacetaldehyde ( 5 ) is prepared by matrix photolysis of ethanesulfenyl chloride ( 3 ) or thiirane ( 4 ) and by flash pyrolysis of allyl ethyl sulfide ( 6 ). Matrix irradiation of 3 or 5 with 222‐nm light results in a dehydrogenation, and a mixture of thiirene ( 7 ), ethynethiol ( 8 ), and thioketene ( 9 ) is formed. Flash pyrolysis of chlorodimethyl sulfide ( 1 ) yields ethenethiol ( 11 ) together with thiirane ( 4 ), whereas ethanesulfenyl chloride ( 2 ) gives ethene under the same conditions. The identification of thioacetaldehyde ( 5 ) is based on the comparison between the experimental and calculated IR spectra.
