chromic

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

为了使的研究简,将阿托品水解为托品醇、再氧为托品,托品季胺盐与氢钠。

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、聚乙醇存在下 ,酸酐和在温和的条件下 ,可以完全转为。

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。
