WebOct 26, 2024 · 1,1-Diaminoazines can act as effective organocatalysts for the formation of phosphorus–carbon bonds between biphenylphosphine oxide and an activated alkene (Michael acceptor). These catalysts provide the P–C adducts at a faster rate and with relatively better yields in comparison to the organocatalysts employed earlier.
