  The present invention discloses processes for producing substituted pyrrole compounds, such as 2,5-disubstituted pyrroles. Synthetic processes which directly convert substituted furan compounds to substituted pyrrole compounds, via a reaction of the substituted furan compound with ammonia and/or an ammonium salt in the presence of a catalyst, also are described.

  本发明揭示了生产取代吡咯化合物的过程，例如2,5-二取代吡咯化合物。还描述了一种合成过程，该过程通过将取代呋喃化合物与氨和/或铵盐在催化剂存在下反应，直接转化为取代吡咯化合物。

  This disclosure provides a process for making transition metal carboxylate compositions by combining in an polar aprotic first solvent a transition metal precursor and a Group 1 or Group 2 metal carboxylate under substantially acid-free and substantially anhydrous conditions, to generate a mixture comprising the transition metal carboxylate composition. Optionally, the transition metal carboxylate composition can be purified, for example, by substantially removing the first solvent provide a residue comprising the transition metal carboxylate composition, and also optionally, further by extracting the transition metal carboxylate composition from the residue with a non-coordinating second solvent to provide an extract comprising the transition metal carboxylate composition.

  本公开提供了一种制备过渡金属羧酸盐组合物的方法，包括在极性无质子的第一溶剂中，在基本无酸和基本无水的条件下，将过渡金属前体和1组或2组金属羧酸盐组合，生成包含过渡金属羧酸盐组合物的混合物。可选地，可以通过基本去除第一溶剂来提纯过渡金属羧酸盐组合物，得到包含过渡金属羧酸盐组合物的残留物，还可以选择性地通过使用非配位的第二溶剂从残留物中提取过渡金属羧酸盐组合物，得到包含过渡金属羧酸盐组合物的提取物。

  Among other things, this disclosure provides an olefin oligomerization system and process, the system comprising: a) a transition metal compound; b) a pyrrole compound having independently-selected C 1 to C 18 organyl groups at the 2- and 5-positions, wherein at least one of the organyl group alpha-carbon atoms attached to the 2- and 5-positions of the pyrrole compound is a secondary carbon atoms; and c) a metal alkyl. For example, the 2,5-diethylpyrrole (2,5-DEP)-based catalyst systems can afford a productivity increases over unsubstituted pyrrole catalyst systems, non-2,5-disubstituted catalyst systems, and 2,5-dimethylpyrrole (2,5-DMP) catalyst systems.

  除其他事项外，本公开提供了一种烯烃寡聚化系统和过程，该系统包括：a）过渡金属化合物；b）在2-和5-位置上具有独立选择的C1到C18有机基团的吡咯化合物，其中至少一个附加在吡咯化合物的2-和5-位置的有机基团的α-碳原子是次级碳原子；以及c）金属烷基。例如，基于2,5-二乙基吡咯（2,5-DEP）的催化剂系统可以比未取代的吡咯催化剂系统、非2,5-二取代催化剂系统和2,5-二甲基吡咯（2,5-DMP）催化剂系统提高生产力。
