Selectivity in the electrophilic addition of carbenes and nitrenes to aliphatic and cyclic sulphides
Abstract
Addition of carbenes CR21(R1= COMe, CO2Me, or CO2Et) to aliphatic and cyclic sulphides to yield sulphonium ylides was highly selective, whereas the addition of nitrenes NR2(R2=p-MeC6H4SO2 or CO2Et) to give iminosulphuranes was quite unselective.
