chromic

1.Oxidation of tropine with chromic oxide gave tropinone which can be quaternized to 5 in quantitative yield.

了使反应的研究简,将阿托品水解托品醇、再氧托品,托品季胺盐与氢钠反应。

2.In the presence of acetic acid and polyethylene glycol, chromic anhydride and acenaphthene react under mild condition and acenaphthene can completely convert into acenaphthenone.

在醋酸、聚乙二醇存在下 ,酸和苊在温和的条件下反应 ,苊可以完全苊。

3.The selective oxidation of ethers by chromic reagent, peroxide, nitric acid, oxygen and ozonide, as well as the ethers anodic oxidation are particularly introduced.

主要介绍了(Ⅵ)类试剂,过氧物、硝酸、氧和臭氧等各类氧剂对醚选择性氧以及醚的阳极电氧研究状况。
