Studies on Heterocyclic Compounds. IV. : Infrared Spectra of Pyrimidine Derivatives

Abstract

Infrared spectra of 34 aminochloropyrimidine derivatives were measured. The NH₂ stretching and deformation frequencies of pyrimidine derivatives were proved to be those of the primary amino group. The skeletal vibration frequencies appeared in the region of 1600∼1520 cm^-1. Discussion were also made on the characteristic deformation frequencies of CH in the pyrimidine ring.
