Qualitative Assessment of the Catalytic Effect of Tertiary Phosphines

The catalytic effect of trialkylphosphine oxides on reaction of diphenylphosphininc hydrazide with phenyl isocyanate in benzene at 25 deg C was evaluated. The catalytic effect was found to be linearly related to the electron-donor factor E, the sum of the Taft constants ?* and the constants ?P of the substituents in the phosphorus atom.
