Provided are nitrogen-doped carbon quantum dots as pyrolysis product of fumaronitrile. The carbon quantum dots may be formed in such a manner that nitrogen may be doped in an amount of 3-10 wt % based on the total weight of the carbon quantum dots with no need for a separate doping process. As a result, the carbon quantum dots have excellent properties, such as optical property, electroconductivity and thermal safety, and thus may be useful for photocatalysts or organic solar cells, or the like.

Several routes for the synthesis of 5-deoxy-D-xylo-hexose have been investigated. Hydrogen in the presence of Raney nickel which had been stirred with an acidic ion-exchange resin converted 5,6-anhydro-1,2-O-isopropyl-idene-α-D-glucofuranose into a mixture of 6-deoxy-1,2-O-isopropylidene-α-D-glucofuranose and 5-deoxy-1,2-O-isopropylidene-α-D-xylo-hexofuranose. Contrary to a previous report, it has
5-脱氧的合成几种途径d -木糖-hexose进行了研究。在阮内镍的存在下,将氢与酸性离子交换树脂一起搅拌,将5,6-脱水-1,2 - O-异丙基-亚烷基-α - D-葡萄糖呋喃糖转化为6-脱氧-1的混合物, 2- ø异亚丙基α- d -glucofuranose和5-脱氧-1,2- ö异亚丙基α- d -低聚木糖-hexofuranose。与先前的报告相反,已显示氢化铝锂对6 - O-苯甲酰基-1,2- O-异亚丙基-5- O-甲苯磺酰基-α- D的作用-glucofuranose给出主要结晶5-脱氧-1,2- ö异亚丙基α- d -低聚木糖-hexofuranose,虽然有人色谱一些6-脱氧-1,2-所示ö异亚丙基β-大号-idofuranose是也形成了。用α-甲苯硫醇钠处理6 - O-苯甲酰基-1,2- O-异亚丙基-5- O-甲苯磺酰基-α- D-葡萄糖呋喃糖,得到6 - S-苄基-1
