Diphenyl phosphate dpp
WebThus, we can know [I] = [EDPP]. As discussed above, DPP acts as a dual-role catalyst and is divided into two parts. One role is to protonate the phosphinite species to establish an equilibrium reaction (equilibrium constant = K), and the other is the residual DPP to activate -CL. Thus, [M*] = [DPP] = [DPP]0 - [EDPP-DPP] can be known. The ...
