Abstract:
1. A method of synthesizing at least one alkyl cyclopentadiene compound, which includes alkyl cyclopentadiene and substituted alkyl derivatives thereof, comprising: contacting at least one cyclopentadienyl anion source which comprises at least one reagent selected from the group consisting of a cyclopentadienyl Grignard reagent, sodium cyclopentadienyl, lithium cyclopentadienyl, potassium cyclopentadienyl, and any combination thereof and at least one alkyl group source which comprises at least one reagent selected from the group consisting of an alkyl halide and an alkyl sulfonate, for 4 to 7 hours at the temperature of 50° C. to 65° C., to form at least one alkyl cyclopentadiene compound; and extracting the alkyl cyclopentadiene compound with a hydrocarbon solvent wherein the mole ratio of the alkyl group source to the cyclopentadienyl anion source is in the range of from 0.5:1 to 0.9:1.
