Physical Data of (S)-Aceto(carbonyl)(cyclopentadienyl)- (triphenylphosphine)iron：mp 142 °C; [α]22 +288° (c 0.004, C6H6), [α]20 +160° (c 0.04, C6H6).

(R)-(-)-ACETYLCARBONYL(ETA5-2,4-CYCLOPENTADIEN-1-YL)(TRIPHENYLPHOSPHINE)IRON is used as chiral acetate enolate equivalent which can be deprotonated with BuLi or LDA in THF at -78 °C; the enolate reacts stereoselectively with a variety of achiral, prochiral, and chiral electrophiles to generate functionalized organoiron compounds from which the iron can subsequently be removed.

(R)-(-)-ACETYLCARBONYL(ETA5-2,4-CYCLOPENTADIEN-1-YL)(TRIPHENYLPHOSPHINE)IRON is soluble in THF, CHCl3, CH2Cl2, acetone.

(R)-(-)-ACETYLCARBONYL(ETA5-2,4-CYCLOPENTADIEN-1-YL)(TRIPHENYLPHOSPHINE)IRON can be stored in air for days with little decomposition. The solid is best stored under nitrogen for long periods of time. More air sensitive when in solution, especially chlorinated hydrocarbons.
