## Abstract Carbon‐13 NMR spectra of the σ‐adduct complexes formed in liquid ammonia between the amide ion and some 2‐R‐pyrimidines, some 4‐chloro‐2‐R‐pyrimidines (R = dimethylamino‐, __N__‐methylanilino, piperidino‐, morpholino‐, phenyl‐), 5‐bromo‐2‐piperidinopyrimidine and pyrimidine itself are d
