摘要: Natural abundance 13C and 15N NMR studies were carried out on a series of N-methylated N-tert-butylated tetrazoles. Long-range 13C,1H 15N,1H coupling constants together with 1J(15N,13C) allowed unequivocal assignments chemical shifts for isomeric 1,5- 2,5-disubstituted © 1997 by John Wiley & Sons, Ltd.
