What is Hexameric Aggregates in Crystalline (Pentamethylcyclopentadienyl)gallium(I) at 200 K about?
## COMMUNICATIONS lenylmetal species without the involvement of chirality transfer or destruction of the allenyl enantiomer. This should become a powerful strategy for the asymmetric synthesis of allenic compounds from racemic allenyl-/propargylmetal species. ## Experimental Section To a solution of the phosphate (0.5 mmol). [Pd(PPh,),] (29 mg. 0.025 mmol. 5 mol%), and the chiral alcohol (0.55 mmol) in anhydrous THF (2.5 mL) was added a 0.1 M solution of samarium(l1) iodide in THF (10 mL, 1.0 mmol) at room temperature under an argon atmosphere. After stirring for 10 min. the reaction mixture was quenched with saturated NH,CI. Standard workup followed by silica gel chromatography afforded the allenic ester 2.
