PHOTO-FRIES REARRANGEMENTS IN N-SULPHONYL CARBAZOLES
Chakrabati, Amit,Biswas, Goutam K.,Chakraborty, D. P.
, p. 5059 - 5064 (2007/10/02)
When photo-Fries rearrangements in N-sulphonyl carbazoles 1 in benzene or methanol smoothly afforded 1- and 3- sulphonylcarbazoles 2 and 3 respectively in 29-55percent yield, N-benzoylcarbazole 1d did not undergo similar rearrangements to give the expected products.
