摘要： A method for preparing a compound comprising a cyclopentadienyl moiety is described. The method comprises: (a) deprotonating a cyclopentadienyl moiety in a solution comprising an alkali hydroxide and a reducing agent; and (b) reacting the deprotonated cyclopentadienyl moiety with a compound having an electrophilic site. Also described is a method of separating a rac-ansa-bridged bis-indenyl transition metal compound of formula (rac-M1) from its meso isomer.
