[2 + 1] cycloaddition reaction of dialkylthioketenes with carbenes - Isomerization of the resulting alkylidenethiiranes

Carbenes generated by metal-catalyzed decomposition of diazo compounds 2 undergo a smooth cycloaddition to the C=S bond of thioketenes 1; products 3 were characterized by spectroscopic means as well as an X-ray structural investigation of 3b. However, photolytic generation of diphenylcarbene from diphenylketene led to an isomeric alkylidenethiirane 4a in the reaction with di-tert-butylthioketene (1a). Analogously, alkylidenethiiranes 3a, b, d, g, h could be photoisomerized to isomers 4a, b, d, g, h. The corresponding rearrangement of S-oxides 8 afforded isomers 9.

Oxidation of Allene Episulfide. Selective Sulfur Oxidation and Novel Isomerization of Resulting S-Oxide

Oxidation of several kinds of substituted allene episulfides was investigated using peracid and singlet oxygen to show an interesting substituent effect on the oxidation products.Thermal and acid-catalyzed isomerization of resulting allene episulfide S-oxide was also described.
