  Chemical Equilibria Study of the Reacting System of the Alkyl Cumyl Ether Synthesis from n-Alkanols and α-Methylstyrene

  摘要：

  The chemical equilibrium of the reactive systems n-alkanol + alpha -methylstyrene double left right arrow alkyl cumyl ether (alkyl is ethyl, propyl, and butyl) was studied in the liquid phase in the temperature range (300 to 383) K using a cation exchanger as heterogeneous catalyst. Equilibrium ratios K-x obtained from concentrations of the reaction participants in the mixtures with an excess amount of alkanol are practically independent of the reactive mixture composition and can be identified with the thermodynamic equilibrium; constant K-a. Enthalpies of reactions Delta H-r(m)o of alkyl cumyl ether synthesis in the liquid phase were obtained from the temperature dependence of K-a and showed a good agreement with those reaction enthalpies derived from the values Delta H-f(m)o(l) of the reactions participants measured for alkyl cumyl ethers by combustion calorimetry. The standard molar enthalpies of vaporization of alkyl cumyl ethers were obtained from the temperature dependence of the vapor pressure measured by using the transpiration method. Resulting values of Delta H-f(m)o(g) were used to prove the consistency of the experimental data and to derive strain enthalpies of alkyl cumyl ethers. The strain effects were discussed in terms of deviations of Delta H-f(m)o(g) from the group additivity rules.

• Nucleophilic Alkoxylations of Unactivated Alkyl Olefins and α‐Methyl Styrene by Photoredox Catalysis

  The photoredox catalytic addition of alcohols to non‐activated terminal alkyl olefins is obtained by the use of N,N‐diisobutylamino‐phenylphenothiazine. Its excited state redox potential is sufficiently high to promote the photoreduction.

  dialkylamino-substituted N-phenylbenzo[b]phenothiazines as alternative photoredox catalysts and applied them for the nucleo­philic addition of alkohols to α-methyl styrene. The additional benzene ring shift the absorbance bathochromically and allows performing the photocatalyses by excitation at 385 nm and 405 nm. This type of photoredox catalysis tolerates other functional groups, as representatively shown

  N-苯基吩噻嗪是一类重要的光氧化还原催化剂，因为它们在合成上很容易获得，它们允许通过不同的取代基调节光电子性能，并且它们具有很强的还原性能以活化烯烃。但是，N-苯基吩噻嗪的主要缺点之一是在UV-A光范围内在365 nm处激发。我们合成了三种不同的二烷基氨基取代的N-苯基苯并[b]吩噻嗪类作为替代的光氧化还原催化剂，并将其用于醇向α-甲基苯乙烯的亲核加成。额外的苯环使吸收度发生红移，并通过在385 nm和405 nm处激发而进行光催化。这种类型的光氧化还原催化作用可耐受其他官能团，
