An efficient and recyclable ionic diphosphine-based Ir-catalyst for hydroaminomethylation of olefins with H2O as the hydrogen source

Abstract

Hydroaminomethylation of olefins with H₂O as the hydrogen source was accomplished over an Ir-catalyst with the involvement of an ionic diphosphine (L6). The use of H₂O as the hydrogen source could completely inhibit the hydrogenation of olefins. The π-accepting ability and improved stability of L6 endowed the corresponding Ir-catalyst with high activity and good longevity for recycling uses.
