Novel photoresponsive axially chiral monophosphine ligands containing azobenzene moiety were prepared and applied to a palladium‐catalyzed allylic alkylation. The reaction of rac ‐1,3‐diphenyl‐2‐propenyl acetate gave the alkylated products with up to 90% enantiomeric excess. The ligand exhibited a trans to cis photoisomerization upon irradiation with UV light. Chirality 14:724–726, 2002. © 2002 Wiley‐Liss, Inc.
