标题:高效可重复使用的由二芳基膦基聚苯乙烯负载的钯催化剂用于cc键形成交叉偶联反应
摘要:描述了可重复使用的由二芳基膦基聚苯乙烯负载的钯催化剂3A-J的短而通用的合成方法.双(ô甲苯基)膦基催化剂3B是用于铃木和的sonogashira交叉偶联特别有效的,而双(米间-甲苯基)膦基催化剂3C是对heck反应中最活跃的催化剂.偶联是在无水反应条件下进行的,仅需少量负载的钯即可(对于铃木宫浦来说,为0.5 Mequivs;对于sonogashira,为1.0 Mequiv.对于heck反应而言,为0.5 Mequivs就足够了).催化剂3A-j 通过过滤回收的废料可以重复使用四次以上,而不会降低效率.

标 题:Synthesis of high molecular weight polybenzimidazole with arylhalo phosphorus compound catalyst
发明人：CHOE EUI W; CONCIATORI ANTHONY B
权利人:CELANESE CORP
摘要:This invention provides a two stage melt polymerization process for the production of an improved type of high molecular weight polybenzimidazole, which involves the use of an arylhalophosphine or arylhalophosphite polymerization catalyst. The process provides poly-2,2'-(m-phenylene)-5,5'-bibenzimidazole of improved color and Plugging Value, and is further characterized by an inherent viscosity of at least about 1.0 dl/g, and a weight average molecular weight of at least about 100,000.
