  Copper Mediated Formation of Carbon-Heteroatom Bonds Using Organoboron Reagents and Ultrasound

  摘要：

  This report summarizes research efforts focused on copper acetate mediated reactions to form new carbon-heteroatom bonds using organoboron reagents under ultrasound irradiation. The method involves the application of ultrasound irradiation to the Chan-Evans-Lam reaction to achieve O-arylation of phenols, N-arylation of anilines and indoles, and S-arylation of thiols. Ultrasound irradiation was found to decrease reaction times from 72 hours to 4 hours while improving the product yields an average of 20%(1) Representative C-O, C-N, and C-S coupling reactions were successfully scaled-up from the milligram to gram levels while maintaining good product yields offering potential applications in industrial processes.

  A flame-retardant polycarbonate resin composition, characterized by comprising a polycarbonate resin (A) and a composite rubbery graft copolymer (B), preferably one obtained by grafting a composite rubber having a structure constituted of 1 to 99 wt. % of a polyorganosiloxane rubber component and 99 to 1 wt. % of a polyalkyl acrylate rubber component, the two components being so interwisted with each other as not to separate from each other, and a mean particle diameter of 0.01 to 0.6 &mgr;m with one or more vinyl monomers, at an (A) to (B) weight ratio of 99:1 to 90:10, and by containing, per 100 parts by weight of the sum total of the components (A) and (B), 0.3 to 1.2 parts by weight (in terms of phosphorus) of a halogen-free phosphoric ester (C) and 0.01 to 1.0 part by weight of polytetrafluoroethylene (D), the weight ratio of the graft copolymer (B) to the phosphorus resulting from the phosphoric ester (C) lying within the range of 2 to 15; and housing of office automation equipment and electrical and electronic appliances and battery packs made by molding the composition. The composition is improved in mechanical properties such as impact resistance, is excellent in moldability and flowability, and exhibits high flame retardance even without resort to any bromine compound.

  一种阻燃性聚碳酸酯树脂组合物，其特征在于由聚碳酸酯树脂（A）和复合橡胶接枝共聚物（B）组成，复合橡胶接枝共聚物最好是通过接枝具有 1 至 99 wt.%聚有机硅氧烷橡胶组分和 99 至 1 wt.%聚烷基丙烯酸酯橡胶组分结构的复合橡胶而获得，这两种组分相互缠绕，不会相互分离，平均颗粒直径为 0.01 至 0.6 &mgr;m的一种或多种乙烯基单体，(A)与(B)的重量比为99:1至90:10，并且每100份重量的组分(A)和(B)的总和中含有0.3至1.2份重量(以磷计)的无卤磷酸酯(C)和0.01至1.0 份（重量）的聚四氟乙烯（D），接枝共聚物（B）与磷酸酯（C）产生的磷的重量比在 2 至 15 的范围内；以及通过模塑该组合物制造的办公自动化设备和电气及电子设备的外壳和电池组。该组合物的机械性能（如抗冲击性）得到改善，成型性和流动性极佳，即使不使用任何溴化合物，也具有很高的阻燃性。
