    • 3 (4.9 g, 0.03 mol)] in THF (70 mL) was added Zn dust ( 2.25 g, 0.035 mol for Co and Cu; 1.95 g, 0.03 mol for Fe) in portions over a period of 15 min. The mixture was stirred at ambient temperature for the period as shown in Table 1. The reaction mixture was then treated successively with water (50 mL) and EtOAc (100 mL), stirred for 10 min more and then filtered. The filtrate was treated with 2% aqueous HCl to dissolve a small amount of suspended particles. The organic layer was separated. The aqueous layer was extracted with EtOAc. The combined organic layer was washed with water, brine and then dried. Solvent removal and column chromatography of the residue (silica gel, 0-15% EtOAc in petroleum ether) afforded 5a/5b as an inseparable mixture, and 5c and 5d in pure form.

    • The partial (Co and Cu) to good (Fe) solubility of the metal salts in distilled THF which always contains some moisture, plays a role in facilitating bimetal redox reactions and subsequent crotylation. It has been observed, that in anhydrous THF no crotylation reaction took place presumably due to the very poor solubility of these metal salts.
