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. The notable advantage is that 1,1-diaminoazines catalyse the reaction even in an aqueous medium with very good yields. Organocatalysis using 1,1-diaminoazines was also successfully carried out between dimethylphosphite and benzylidenemalononitrile under multicomponent conditions.
