  This disclosure relates to methods for production of aromatic esters useful as plasticizers without using esterification catalyst, to the aromatic esters, and to polymer compositions containing the aromatic esters. It also relates to producing aromatic polyesters without using esterification catalyst. The aromatic esters and polyesters can be produced catalyst-free by esterifying carboxylic acids with alcohol(s) at high temperature and high pressure, namely at a temperature from 100°C to 350°C and a pressure ≥ 100 psig, preferably ≥ 600 psig. The aromatic esters and polyesters can also be produced by esterifying without esterification catalyst carboxylic acids with methyl or ethyl alcohol, separating the resulting methyl or ethyl esters from the carboxylic acid and any byproduct impurities, and then transesterifying with or without esterification catalyst the methyl or ethyl esters with alcohols and/or diols.

  这份披露涉及生产芳香酯的方法，这些芳香酯可用作增塑剂，而无需使用酯化催化剂，还涉及到含有这些芳香酯的聚合物组合物。它还涉及在不使用酯化催化剂的情况下生产芳香聚酯。这些芳香酯和聚酯可以通过在高温高压下，即在温度为100°C至350°C、压力≥100 psig（最好≥600 psig）的条件下，无需催化剂地通过羧酸与醇的酯化来生产。这些芳香酯和聚酯也可以通过在不使用酯化催化剂的情况下，将羧酸与甲醇或乙醇酯化，将产生的甲醇或乙醇酯与羧酸和任何副产物杂质分离，然后通过酯化或不酯化催化剂与醇和/或二醇进行酯交换来生产。

  5-membered alicyclic α-amino acids bearing a (2-phenyl)benzoyl protective group to acrylonitrile under mild organic photoredox catalysis conditions furnished γ-amino acid derivatives with high retention of chirality via the memory of chirality (MOC) strategy. The retention of chirality in the photoinduced decarboxylation was strongly dependent on the structure of the alicyclic α-amino acids and alkenes. To

  Fusion of benzhydrols to give fluorenols is found to not affect the electronic susceptibility of substitution reactions suggesting the antiaromaticity of the intermediate serves simply to slow the process.
