: Cr(CO)C₇H₇(P(C₆H₅)2CH₂P(C₆H₅)2)⁽¹⁺⁾*BF₄^(1-)=Cr(CO)C₇H₇(P(C₆H₅)2CH₂P(C₆H₅)2)(BF₄)

Guidance literature:: In acetone; under N2; equimolar mixt. of the phosphine and the Cr-complex refluxed in acetone for 3 h; evapn., residue dissolved in CH2Cl2, chromy. (alumina) elution with CH2Cl2 gave Cr(CO)3-complex, elution with CH2Cl2/CH3CN (60/40) followed by dropwise addn. Et2O (crystn.) gave Cr(CO)-complex, elution with C6H6 gave Cr(CO)4-complex, elem. anal.;
