Abstract

Cyclization of 1-Isothxocyanato-2-thiocyanates J. Org. Chem., Vol. 42, No. 9, 1977 1517 tions at 1488 cm-l.] Replacement of chloride ion for the methanesulfonate group did not result in any significant shifts in the positions of these two bands. Infrared spectra of the hydromethanesulfonate salts3 as KBr pellets showed an absorption band at 1570 (2m-l for the> C= N group and at 1480 cm-l for the-NH2 group. A detailed analysis of the lH NMR ...
