  Problem to be Solved: To provide an axially asymmetric optically active biarylphosphorus compound that can easily produced without the step of optical resolution which was almost indispensable in conventional methods. Solution: A method for producing an axially asymmetric phosphorus compound represented by the general formula (1), comprising a cycloaddition reaction of a compound having a triple bond with the use of a catalyst containing rhodium metal and an optically active bisphosphine. (In the formula, J is an oxygen atom, a sulfur atom or BH 3 ; R 1 and R 2 independently are an alkyl, cycloalkyl, aryl, alkoxy and aryloxy group; a1 and a2 independently are 0 or 1; R 3 to R 10 independently are an alkyl, cycloalkyl, aryl, alkoxy and aryloxy group; two among R 3 to R 10 may form a ring; and * is axial asymmetry.)
