Reversible P–C bond formation for saturated α-aminophosphine ligands in solution: stabilization by coordination to Cu(I)
Abstract
The saturated α-aminophosphine ligands containing a secondary amine function Ph2PCH(R′)NHR″ establish a solution equilibrium with Ph2PH and R′CH2NR″ and are stabilized by electron-withdrawing substituents R′ and R″ and by coordination of the phosphorous donor to Cu(I).
