Nitrile sulphide formation from the thermal fragmentation of 1,3,4-oxathiazoles: a retro-1,3-dipolar cycloaddition
Abstract
1,3,4-Oxathiazoles, on thermolysis, undergo retro-1,3-dipolar cycloaddition to afford carbonyl compounds and nitrile sulphides, which may be trapped by cycloaddition with alkynes and nitriles.
