Abstract

<jats:title>Abstract</jats:title> <jats:p>The vanadium(V)(salalen) complex prepared in situ from the corresponding vanadium(IV) complex 4 under aerobic conditions was found to be an excellent catalyst for asymmetric transcyanation of aliphatic aldehydes with acetone cyanohydrin as the cyanide source, showing high enantioselectivity of 91–95% ee.</jats:p>
