Electric Literature of 626-18-6, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 626-18-6, name is 1,3-Benzenedimethanol. A new synthetic method of this compound is introduced below.
Example 6Direct Single-Stage Amination of Alcohols andHydroxy Acids by Means of Ammonia Over aHomogeneous Ruthenium Catalyst and Xantphos ata high V7J Vgas (according to the invention)Under an argon atmosphere, m g of starting material, mRU g of [carbonylchlorohydridotris(triphenylphosphane)ruthenium(II)] and mp g of 9,9-dimethyl-4,5-bis (diphenylphosphino)xanthene as catalyst and V07 ml of 2-methyl-2-butanol as solvent were introduced into a 50 mlsteel tube. The vessel was closed, pressurized three times with 20 bar of argon and depressurized each time. The vessel was then cooled by means of dry ice and m g of ammonia were condensed in. The reactor is heated to T C. and maintained at this temperature for 20 hours. Afier cooling to room temperature, the reactor was depressurized and opened, the solvent was removed on a rotary evaporator and the residue was dissolved in methanol and then analysed by gas chromatography. Reaction parameters and conversions and selectivities to the desired reaction product are shown in Tab. 5. The results show that many different hydroxy-thnctionalized substrates can be aminated by the method described.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,626-18-6, 1,3-Benzenedimethanol, and friends who are interested can also refer to it.
