Abstract

2-Nitroindole undergoes addition reactions with the radicals generated from active CH compounds upon treatment with Mn (OAc) 3· 2H2O to afford the corresponding 3-substituted- 2-nitroindoles in 27–66% yields. Products of the methylene addition reactions undergo a subsequent in situ Nef reaction to afford 2-oxoindolin-3-ylidenes.
