J. Andrieu et al., Reversible P-C bond formation for saturated alpha-aminophosphine ligands in solution: stabilization by coordination to Cu(I), NEW J CHEM, 23(6), 1999, pp. 581-583
The saturated alpha-aminophosphine ligands containing a secondary amine fun
ction Ph2PCH(R')NHR " establish a solution equilibrium with Ph2PH and R'CH=
NR " and are stabilized by electron-withdrawing substituents R' and R " and
by coordination of the phosphorous donor to Cu(I).
