sodium methoxide การใช้

• A classic case is sodium methoxide produced by the addition of sodium metal to methanol:
• Triethyl phosphonoacetate can be added dropwise to sodium methoxide solution to prepare a phosphonate ylide.
• Nitric oxide can also react directly with sodium methoxide, forming sodium formate and nitrous oxide.
• In the second step, the salt is treated with base, such as sodium methoxide.
• Sodium methoxide is conveted practically instantly to sodium hydroxide and methanol in the presence of water.
• The structure, and hence its basicity, of sodium methoxide in solution depends on the solvent.
• It is synthesized by a reaction between methyl 2-keto-D-gluconate and sodium methoxide.
• In one modification, d-glucose is converted to the glucose oxime by reaction with hydroxylamine and sodium methoxide.
• The reaction is performed in dry methanol with sodium methoxide, and the product is obtained in 55 % yield.
• They began to look for a cheaper synthesis and discovered that adding methyl borate to sodium hydride at 250?produced sodium borohydride and sodium methoxide.
• It may be synthesized from benzoic acid and hydrogen peroxide, or by the treatment of benzoyl peroxide with sodium methoxide, followed by acidification.
• The 5-methoxytriazole precursor to this carbene was made by the treatment of a triazolium salt with sodium methoxide, which attacks as a nucleophile.
• Sodium methoxide, for example, is commonly used for this purpose, a reaction that is relevant to the production of " bio-diesel ."
• In the solid form, sodium methoxide is polymeric, with a sheet-like arrays of Na + centers, each bonded to four oxygen centers.
• So for example, sodium methoxide can produce the 6, 6-dimethoxy-1, 3-dinitro-1, 3-cyclohexadiene anion.
• This compound is converted to the diazo ketone "'5 "'by deprotonation ( using acetic acid and sodium methoxide ) and reaction with tosyl azide.
• A single ketone can also be converted to the corresponding alkene via its tosylhydrazone, using sodium methoxide ( the Bamford Stevens reaction ) or an alkyllithium ( the Shapiro reaction ).
• Industrial methyl formate, however, is usually produced by the combination of methanol and carbon monoxide ( carbonylation ) in the presence of a strong base, such as sodium methoxide:
• The resulting solution, which is colorless, is often used as a source of sodium methoxide, but the pure material can be isolated by evaporation followed by heating to remove residual methanol.
• In the final step sodium methoxide in methanol is added, leading to removal of all the acetate groups and ejection of the nitrile group and collapse of the second carbon from a tetrahedral structure to an aldehyde.
