A flame retardant thermoplastic composition that includes a polycarbonate or polycarbonate blend resin, a non-brominated, non-chlorinated flame retardant package, a carbon-containing synergist, such as carbon black and an optional reinforcing filler. The composition provides high impact resistance, improved flame retardant characteristics, and/or good processing during injection molding (i.e. mold-ability), while complying with regulations that restrict the use of halogenated materials. These compositions may be used, for example, to injection-mold big or complex parts that are used in objects that are beneficially flame-resistant and/or do not break when an accidental impact occurs during usage or transportation.

Electrochemical dehydrogenative C–O bond formation for the synthesis of sultones was achieved. In the presence of K2CO3 and H2O, constant current electrolysis of [1,1′-biphenyl]-2-sulfonyl chloride afforded an aryl-fused sultone quantitatively. Under the optimized conditions, a variety of sultone derivatives were obtained. Control experiments suggest that the electrochemical oxidation of the sulfonates
实现了用于合成磺内酯的电化学脱氢 C-O 键形成。在K 2 CO 3和H 2 O存在下,恒流电解[1,1'-联苯]-2-磺酰氯定量得到芳基稠合磺内酯。在优化条件下,得到了多种磺内酯衍生物。对照实验表明,原位产生的磺酸盐的电化学氧化会提供磺基中间体。
