polymer supported hydrogen fluoride in methylene chloride proceeds with Markovnikov type regioselectivity. Fluorination and halofluorination of norbornene with xenon difluoride or N-bromosuccinimide or N-chlorosuccinimide in the presence of polymer- supported hydrogen fluoride resulted in up to five products, with a large increase in halonortricyclane formation, compared to reactions in the presence
通过氟化氢与含有40-45 mol%4-乙烯基吡啶的交联聚(苯乙烯-4-乙烯基吡啶)的反应制备的聚合物支撑的氟化氢不与-苯乙烯,1,2-二苯基乙炔和环己醇在各种条件下,而1-苯基-1-羟基-4-叔丁基环己烷已转化为1-苯基-4-叔丁基环己烯。在聚合物负载的氟化氢存在下,在二氯甲烷中用N-溴代琥珀酰亚胺对各种苯基取代的烯烃进行溴氟化,以马尔可夫尼科夫类型区域选择性进行。与存在氟化氢-吡啶。与氟化氢-吡啶相比,聚合物负载的氟化氢增强了 氟化物或卤代氟化物对亲电试剂对降冰片二烯的攻击。
