Oxygen-sulfur rearrangement in the reaction of thiocarbamate imidazolium ylide with arylaldehyde
The nucleophilic addition of thiocarbamate imidazolium ylide to aldehyde triggered sequential intramolecular N to O migration of thiocarbonyl amide group and reversible oxygen-sulfur rearrangement to afford 2-imidazolium alkylcarbamothioate. The ortho gro
