摘要:描述了邻位-溴-联苯-三甲基硅烷与四丁基氟化铵(tbaf)进行甲硅烷基化过程中芳环系统的异常芳烃介导的氟化反应.在一个芳炔和加成氟化物得到的原位形成氟化联苯.通过suzuki-Miyaura交叉耦合和x射线分析合成的真实样品无疑证实了该结构.用呋喃进行的原位捕集实验证明了氟化物引起的tms基团的置换和随后的溴化物消除,造成了芳烃的短暂形成.

摘要:Ligand synthesis methods for the preparation of ligands having the formula n nwherein Q is selected from phosphorus, arsenic and antimony; wherein X 1 , X 2 and X 3 are carbon anions; and, wherein R 15 is selected from —SO 3 , —SO 2 N(R 18 ), —CO 2 , —PO 3 , —AsO 3 , —SiO 2 , —C(CF 3 ) 2 O; where R 18 is selected from a hydrogen, a halogen, a hydrocarbyl group and a substituted hydrocarbyl group, are disclosed. Also disclosed are methods of complexing the ligands with late transition metals to form catalyst complexes that catalyze polymerization reactions and/or Heck coupling reactions.
