Flash vacuum pyrolysis of 1,3-oxathiolan-5-ones causes loss of carbon dioxide with the concominant formation of the corresponding thiiranes in nearly quantitative yield.The reaction is stereospecific and proceeds by clean inversion of configuration.This suggests a concerted loss of carbon dioxide.Furthermore, substituent effects strongly support the intermediacy of thiocarbonyl ylides.Consequently, this method becomes one of the simplest ways of generating these species.
