Meoh reaction

WebGeneral description. The product is 25wt.% solution of sodium methoxide in methanol. Its reaction with unactivated aryl bromides in the presence of copper catalyst under various reaction conditions has been studied. [ 1] It reacts with aryl halides in the presence of a palladium catalyst in DMF (Dimethylformamide) to afford arenes. WebH2SO4/MeOH system, and the remainder with the HCl/MeOH system. Conclusions We have developed a facile method to synthesize different amino acid methyl ester hydrochlorides through the esterification of corresponding amino acids with methanol using trimethylchlorosilane. The reaction offers convenience, mild conditions and good to …
