Abstract: A regioselective process is provided for preparing 4-bromo-o-xylene in an isomer mixture of 4-bromo-o-xylene and 3-bromo-o-xylene by combining a molar excess of bromine with o-xylene. The produced 3-bromo-o-xylene isomer preferentially reacts with the excess bromine to produce dibromo-o-xylenes. The weight ratio of the 4-bromo-o-xylene to the 3-bromo-o-xylene in the product isomer mixture can be as high as about 97:3. Concurrent production of alpha-bromo-o-xylene is avoided by conducting the admixing in either darkness or in sulfur dioxide solution. The dibromo-o-xylene by-products are easily separated by subsequent vacuum distillation or similar expedients. The use of small amounts of sulfur dioxide also provides for enhanced selectivity for the formation of 4-bromo-o-xylene relative to 3-bromo-o-xylene even when the mole ratio of bromine to o-xylene is 1:1 and lower.

Abstract translation: 提供了一种区域选择性方法，通过将摩尔过量的溴与邻二甲苯组合，在4-溴 - 邻 - 二甲苯和3-溴 - 邻二甲苯的异构体混合物中制备4-溴 - 邻二甲苯。 所产生的3-溴 - 邻二甲苯异构体优先与过量的溴反应生成二溴 - 二甲苯。 产物异构体混合物中4-溴 - 邻二甲苯与3-溴 - 邻 - 二甲苯的重量比可以高达约97:3。 通过在黑暗或二氧化硫溶液中混合来避免同时生产α-溴代邻二甲苯。 通过随后的真空蒸馏或类似的方法容易地分离出二溴邻二甲苯副产物。 即使当溴与邻二甲苯的摩尔比为1:1时，使用少量的二氧化硫也提供了相对于3-溴 - 邻二甲苯形成4-溴 - 邻二甲苯的增强的选择性 。

Abstract: The invention describes a novel process for the preparation of polycarbonate and/or polyarylate block copolymers with poly(aryl ethers). The process is comprised of steps: (a) the reaction of a dihydroxy-terminated poly(aryl ether) oligomer with a high molecular weight polycarbonate, or a high molecular weight polyarylate, or a high molecular weight poly(arylate-carbonate) to yield a block copolymer; followed by (b) the coupling of the material obtained in step (a) to the required molecular weight, using a diaryl ester of carbonic acid or of a dicarboxylic acid. Both steps are performed in the presence of a catalyst. The copolymerizations can be run in bulk under vacuum in a single or twin screw extruder. Using the above conditions high molecular weight, high quality block copolymers having a combination of excellent properties are obtained in a matter of minutes.
