Nitrosation of 2-Arylamino- and Alkylamino-2-thiazolines
Rao, K. V.,Nizar, P. N. H.,Chauhan, S. M. S.
, p. 974 - 976 (2007/10/02)
The N-nitrosation of 2-arylamino- and alkylamino-2-thiazolines gives the exocyclic or endocyclic nitrosated products depending on the nature of reagents used.The structures of these nitrosoproducts have been confirmed by PMR and 13C NMR spectral data.
