  • Phosphine transition metal complex, method for producing same, and anticancer agent
    Patent number: 11180516
    Abstract: The phosphine transition metal complex of the present invention is represented by formula (1). Preferably, R1 and R6 are identical groups, R2 and R7 are identical groups, R3 and R8 are identical groups, R4 and R9 are identical groups, R5 and R10 are identical groups, and n and y are identical numbers. The phosphine transition metal complex is suitably obtained by reacting a phosphine derivative represented by formula (2) and a phosphine derivative represented by formula (3) with a salt of a transition metal of gold, copper or silver. See the description for the meanings of the symbols in each formula.
