The overall neutral α-borylated phosphorus ylide PhPC(Me)BEt behaves like a polar borataalkene and can act as acyclic, ambiphilic π-type ligand with L- and Z-type functionalities side by side. In the complexes [MX{η-PhPC(Me)BEt}] (M = Cu, (Ag), Au; X = Cl, NTf), the bonding is dominated by the highly nucleophilic ylidic carbon atom (L-type ligand). The Lewis acidic boron atom furnishes nonetheless a small but significant bonding contribution (Z-type ligand).
