Notizen:
Proton NMR spectra are reported for 15N enriched borazine and a series of 15N enriched derivatives: N-methyl-borazine, N,N′-dimethylborazine and a new photochemical product, 1-methyl-2-aminoborazine. Chemical shifts for the ring (15N—H) protons have been measured. Using a Fourier transform spectrometer, fine structure in the 15N—H doublet is resolved. Ortho and meta ring proton and three-bond 15N 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.
