PURPOSE:To obtain the titled compound useful as a catalyst for organic syntheses and high polymer reactions by a simple operation without using expensive reagents, by reacting bis(diphenylphosphino)amine with a Grignard reagent and reacting the reaction product with a halide compound. CONSTITUTION:A compound shown by formula I is reacted with a Grignard reagent shown by the formula R'MgX' (R' is alkyl or aryl; X' is Cl, Br or I) in an equimolar ratio, preferably in a little excess amount, in an organic solvent such as THF, etc., under heating and the prepared reaction product shown by formula II is reacted with 2mol based on the reaction product of a halide compound shown by formula RX (R is alkyl or benzyl; X is Cl, Br or I) under reflux by heating for 5-10hr to give a bis(alkyldiphenylphosphine or benzyldiphenylphosphine)iminium salt shown by formula III.
