Abstract
Proton NMR spectra are reported for ^15^N enriched borazine and a series of ^15^N enriched derivatives: N‐methyl‐borazine, N,N′‐dimethylborazine and a new photochemical product, 1‐methyl‐2‐aminoborazine. Chemical shifts for the ring (^15^NH) protons have been measured. Using a Fourier transform spectrometer, fine structure in the ^15^NH doublet is resolved. Ortho and meta ring proton and three‐bond ^15^N to H coupling constants have been determined. Substituent effects on chemical shifts and coupling constants for borazine derivatives are compared with those for analogous benzene derivatives.
