Reaction of chlorosulfonyl isocyanate (CSI) with nitrones a-n and a,b has been studied. α, α, N-Triaryl nitrones a-n react with CSI to form the N,N-diaryl arylamides a-n and i-n in good yields. In the case of α-H, α, N-diaryl nitrones a,b however, two compounds viz., the rearranged product a,b and the 1,4-dihydro tetrazines a,b are formed.
