synthesized from aldehydes or ketones and allylicacetates, using an electrochemical process catalyzed by iron complexes. We first studied the reactivity of allyl acetate, using N,N-dimethylformamide (DMF) or acetonitrile (AN) as solvent, FeBr(2) as catalyst, and Fe as the sacrificial anode. Then we tested the regioreactivity of crotyl acetate and other allylic derivatives.
Allylation of ketones has been efficiently performed using iron-complex catalysis and led to homoallylic alcohols in high yields. (c) 2006 Elsevier Ltd. All rights reserved.
