Nitrogen-15 NMR: iminothiol-thioamide tautomerism of 2-mercaptobenzazoles and 1-methyl-2-mercaptoimidazole: Nitrogen-15 NMR: iminothiol-thioamide tautomerism of 2-mercaptobenzazoles and 1-methyl-2-mercaptoimidazole. Balestrero, R. S.; Forkey, D. M.; Russell, J. G. (Dep. Chem., California State Univ., Sacramento, CA 95819, USA). Magn. Reson. Chem., 24(8), 651-5 (English) 1986. CODEN: MRCHEG. ISSN: 0749-1581. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Section cross-reference(s): 77 The 15N and 13C NMR spectra of a no. of 2-mercaptoazoles were obtained and the position of the iminothiol-thioamide prototropic tautomeric equil. was detd. Because of the large chem. shift difference of ~100 ppm between the iminothiol and thioamide N atoms, the 15N chem. shifts of the S-Me and N-Me analogs of each tautomer provided reasonable chem. shift models for the same N atom in the tautomers. 583-39-1 is just another one chemical used in this study. Only a small correction for an N-Me effect was required. .
