Bis(eta-cyclopentadienyl) iron → HCID 178440574, compound

Participants

Reaction Steps

The general procedure of Example 1 is followed using 3.5 g (18.8 mmol) of ferrocene in 30 mL of hexane, 25 mL of a 1.6M hexane solution of n-butyl lithium, 4.5 g (38.7 mmol) of N,N,N',N'-tetramethylethylenediamine and 20 g (41 mmol) of 2,4,8,10-tetrakis(tert-butyl)-6-chloro-12H-dibenzo[d,g][1,3,2]dioxaphosphocin in 100 mL of tetrahydrofuran. The residue is triturated with hexane and the resultant solid is recrystallized from an acetonitrile/tetrahydrofuran mixture to give 12 g (58.5% yield) of a light brown solid.
