A comparative study has been made of UV/V-spectra of substituted 3H-phenoxazin-3-ones and phenoxazines which are obtained on reduction. For the bathochromic shift of the longwave absorption band of the ommochromes and of some phenoxazinones on reduction the 2-amino-/2-hydroxy-/2-methoxy-1-acetyl-3H-phenoxazinon-(3)-structure isnecessary.
对还原后获得的取代的3H-
吩恶嗪-3-酮和
吩恶嗪的UV / V光谱进行了比较研究。对于全色
染料和某些苯并恶嗪酮的长波吸收带的红移,还原时需要2-
氨基/ 2-羟基-/ 2 /甲氧基-1-乙酰基-3H-苯恶嗪酮-(3)-结构。
