    摘要： 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 a hydrogen atom on at the 5-position or the 2- and 5-position of a pyrrole compound and having a bulky substituent located on each carbon atom adjacent to the carbon atom bearing a hydrogen atom at the 5-position or the 2- and 5-position of a pyrrole compound. These catalyst system have significantly improved productivities, selectivities to 1-hexene, and provides higher purity 1-hexene within the C6 fraction than catalyst systems using 2,4-dimethylpyrrole.

    摘要： Compounds having the formula: 1 are disclosed. M1 and M2 are the same or different and are transition metal atoms or ions; Z2 and Z3, independently, are the atoms necessary to complete a 3-12 membered heterocyclic ring; Z1 is an alkylene or arylene group; Ql and Q2 are the same or different and are electron withdrawing groups; L1 and L3, taken together, represent nullOnullCR13nullOnull; L2 and L4, taken together, represent nullOnullCR14nullnullOnull; and R13 and R14 are the same or different and are selected from the group consisting of alkyl groups and aryl groups or R13 and R14 represent alkylene or arylene groups that are directly or indirectly bonded to one another. Methods for making such compounds are also disclosed, as are intermediates which can be used in their preparation. Also disclosed are methods for carrying out CnullH insertion reactions using bis-transition metal catalysts, such as the above compounds. Procedures for preparing d-threo methylphenidate, tolterodine, CDP-840, nominfensine, and sertraline, are described.
