N‑Heterocyclic Carbene-Supported Cuprous Phosphaethynolates and Their P-atom Transfer
Low-coordinate Cu(I) ions play an important and varied role in organic synthesis, including the reduction of Michael acceptors and catalysis of azide–alkyne cycloadditions. The phosphaethynolate anion (i.e., PCO–) has similarly found a growing role as a P-atom transfer reagent. The convergence of these two topics, whil...
