Abstract

<jats:title>Abstract</jats:title> <jats:p>2-Iodobenzamides reacted with alkynes in the presence of a nickel(0)/P(4-ClC6H4)3 catalyst to produce substituted (1H)-isochromen-1-imines. The reaction proceeded through the formation of an oxanickelacycle, alkyne insertion, and reductive elimination.</jats:p>
