A study on the quality of AMMONIA-FUMIGATED diazo printing paper of moderate speed 提高重氮氨熏中速晒图纸质量的研究
New methods for the synthesis of α-halo-α, β-unsaturated and α-diazo carbonyl compounds have been investigated in this paper. In addition, the O-H insertion reaction of the α-diazo carbonyl compounds has been exploited. 本论文探讨了α-卤代-α,β-不饱和酯的新合成方法以及α-重氮羰基化合物的合成与O-H插入反应。
