    Alkyl Methyl Carbonates as Methylating Agents. The O-Methylation of Phenols
    摘要:
    多种酚类(ArOH:Ar = Ph,p-CH3C6H4,p-ClC6H4,o-和p-CH3COC6H4,以及2-萘基)的O-甲基化反应可以通过使用不对称烷基甲基碳酸酯CH3OCOOR(R = n-Pr,3b;n-Bu,3d;CH3O(CH2)2O(CH2)2,3e)作为烷基化剂,以高选择性方式进行。例如,在150°C下,使用2-(2-甲氧基乙氧基)乙基甲基碳酸酯3e并在K2CO3存在下,苯酚可以在4.5小时内定量转化为茴香醚。与使用二甲基碳酸酯的甲基化反应需要密封加压反应容器相比,不对称烷基甲基碳酸酯允许在常压下进行更为简单和安全的烷基化反应。选择性O-甲基化几乎不受温度(120-150°C)影响,但其取决于溶剂的性质和用量。DMF和三甘醇二甲醚已被证明是较好的反应介质。

    Selective N,N-Dimethylation of Primary Aromatic Amines with Methyl Alkyl Carbonates in the Presence of Phosphonium Salts
    摘要:
    In the presence of onium salts, at 140-170 degrees C, methyl alkyl carbonates [1a-c, ROCO2Me, R) MeO(CH2) 2[O(CH2)(2)](n); n = 2-0, respectively] react with primary aromatic amines (XC6H4NH2, X = p-OMe, p-Me, H, p-Cl, p-CO2Me, o-Et, and 2,3-Me2C6H3NH2) to yield the corresponding N,N-dimethyl derivatives (ArNMe2) with high selectivity ( up to 96%) and good isolated yields (78-95%). Phosphonium salts ( e. g., Ph3PEtI and n-Bu4PBr) are particularly efficient catalysts. Overall, a solvent-free reaction is coupled with safe methylating agents (1a-c) made from nontoxic dimethyl carbonate.

    In the presence of a Na-exchanged Y faujasite, the reaction of primary aromatic amines 1 with 2-(2-methoxyethoxy)methylethyl carbonate [MeO(CH(2))(2)O(CH(2))(2)OCO(2)Me, 2a] yields the corresponding mono-N-methyl derivatives ArNHMe with selectivity up to 95%, at substantially quantitative conversions. At 130 degrees C, the reaction can be run under diffusion-free conditions and is strongly affected

    transesterification reactions. Aromatic substituents, however, modify the relative reactivity of amines 1−4: good evidence suggests that, not only steric and electronic effects, but, importantly, direct acid−base interactions between substituents and the catalyst are involved. Weakly acidic groups (OH, CH2OH, CONH2, pKa ≥ 10) may help the reaction, while aminobenzoic acids (pKa of 4−5) are the least reactive
