13 C n.m.r. spectral data of pteridine and nineteen of its derivatives (containing one or more chloro, methylthio, methyl, t ‐butyl or phenyl substituents) are reported. The 13 C n.m.r. spectrum of the title compound has been assigned conclusively. 13 C n.m.r. substituent effects are shown to be very useful in discerning between 6‐ and 7‐substituted pteridines. Additionally, the 13 C n.m.r. spectra of several covalent amination products, i.e. the 3,4‐dihydro‐4‐ amino‐ and the 5,6,7,8‐tetrahydro‐6,7‐diaminopteridine derivatives, formed by dissolving the appropriate pteridine in liquid ammonia, have been recorded. The 13 C n.m.r. spectra of the corresponding covalent hydrates are also reported.
