标 题:Arene-transition metal linkers for solid phase synthesis
发明人：GALLOP MARK A
权利人:GLAXO WELLCOME INC
摘要:Compositions and methods for the solid phase synthesis of organic compounds are provided. The compositions are solid supports having an attached traceless linker precursor and are represented by the formula: ##STR1## In this formula, S 0 is a solid support; B is a connecting group; M is a transition metal, for example ruthenium, chromium, iron, molybdenum and manganese; each L is independently a transition metal ligand; the letter n represents an integer of from 1 to 4, such that M has a sufficient number of ligands to fill the available valences; and X - represents an anion which is typically a non-nucleophilic anion.

标题 :Synthesis of alkyl cyclopentadiene compounds
发明人：HARLAN C JEFF; CAO XIANYI; RIX FRANCIS C
权利人:HARLAN C JEFF; CAO XIANYI; RIX FRANCIS C; UNIVATION TECH LLC
摘要:A method of synthesizing an alkyl cyclopentadiene compound is disclosed. The method includes contacting at least one cyclopentadienyl anion source and at least one alkyl group source to form at least one alkyl cyclopentadiene compound. The method further includes extracting the alkyl cyclopentadiene compound with a hydrocarbon solvent. The alkyl cyclopentadiene compound may be converted to a metallocene catalyst compound.
