A general and efficient Cu(II)-catalyzed cross-coupling method is reported for the preparation of acyclic tertiary amides. Generally moderate to excellent yields and functional group tolerance were obtained with secondary acyclic amides and aryl halides as substrates in toluene.

Reaction of chlorosulfonyl isocyanate (CSI) with nitrones 1a-n and 5a,b has been studied. α,α,N-Triaryl nitrones 1a-n react with CSI to form the N,N-diaryl arylamides 3a-n and 4i-n in good yields.In the case of α-H,α,N-diaryl nitrones 5a,b however, two compounds viz., the rearranged product 11a,b and the 1,4-dihydro tetrazines 10a,b are formed.The effect of substituents on the rearrangement has been studied.It is found that the nature of the substituents has got a profound effect on the rearrangement.We have also noted that the rearrangement is independent of the syn or anti configurations of the nitrones.
