Sr[C5(CH3)4(C3H7)]2 is prepared by reacting Na[C5(CH3)4(C3H7)]2 or K[C5(CH3)4(C3H7)]2 with SrI2 in THF to produce a THF adduct of Sr[C5(CH3)4(C3H7)]2; evaporating THF and extracting the residue with toluene to give a toluene solution; evaporating toluene and drying the residue under reduced pressure; and heating to 100 to 160° C. in vacuo to dissociate and remove THF and distilling.
