摘要

NOTES J. Org. Chem., Vol. 36, No. g2, 1971 3473 the uv absorption and Cotton effect are in the region 230-240 mp14, x5, 18 and no absorption at longer wavelengths corresponding to n+ a* transitions of the> C= N-group have been reported. As well as the low intensity long wavelength bands which we have attributed to n+ a* transitions of the carbonyl groups, our uv spectra also show for 3 a maximum at 235 mp and for 2 a shoulder at approximately ...
